BACKGROUND OF THE INVENTION

0005Field of the Invention

0006[0002] The present invention is directed to protected substrates and to methods for protecting a substrate.

0007Description of Related Art

0008[0003] Large substrates, such as large glass sheets, often become damaged during shipment from the manufacturing plant to the customer site. This results in a substrate unsuitable for installation, causing chargebacks to the manufacturer and delay to the construction project. One way to protect large substrates from damage is to overlap, or hold together using tape, two smaller protective sheets positioned over the large substrates.

0009[0004] This approach includes certain drawbacks. For example, a small capillary tube can be formed at the seam of the two smaller protective sheets over which the tape is applied. The small capillary tube attracts water that induces corrosion at the site of the seam, which results in damage requiring chargebacks and project delays. Therefore, a protected substrate that prevents damage to a large substrate during shipment, including corrosion damage induced at the seam of overlaying protective sheets, is desired.

0029DESCRIPTION OF THE INVENTION [0023] For purposes of the description hereinafter, the terms “end”, “upper”, “lower”, “right”, “left”, “vertical”, “horizontal”, “top”, “bottom”, “lateral”, “longitudinal”, and derivatives thereof shall relate to the invention as it is oriented in the drawing figures. However, it is to be understood that the invention may assume various alternative variations and step sequences, except where expressly specified to the contrary. It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification, are simply exemplary embodiments or aspects of the invention. Hence, specific dimensions and other physical characteristics related to the embodiments or aspects disclosed herein are not to be considered as limiting.

0030[0024] For purposes of the following detailed description, it is to be understood that the invention may assume various alternative variations and step sequences, except where expressly specified to the contrary. Moreover, other than in any operating examples, or where otherwise indicated, all numbers used in the specification and claims are to be understood as being modified in all instances by the term “about”. Accordingly, unless indicated to the contrary, the numerical parameters set forth in the following specification and attached claims are approximations that may vary depending upon the desired properties to be obtained by the present invention. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical parameter should at least be construed in light of the number of reported significant digits and by applying ordinary rounding techniques.

0031[0025] It should be understood that any numerical range recited herein is intended to include all sub-ranges subsumed therein. For example, a range of “1 to 10” is intended to include all sub-ranges between (and including) the recited minimum value of 1 and the recited maximum value of 10, that is, having a minimum value equal to or greater than 1 and a maximum value of equal to or less than 10.

0032[0026] With respect to layers of material described herein, the term “over” means farther from the substrate on which the material is positioned. For example, a second layer positioned “over” a first layer means that the second layer is positioned farther from the substrate than is the first layer. The second layer may be in direct contact with the first layer. Alternatively, one or more other layers may be positioned between the first layer and the second layer.

0033[0027] The terms “polymer” or “polymeric” include oligomers, homopolymers, copolymers, and terpolymers, e.g., polymers formed from two or more types of monomers or polymers. As used herein, the term “resin” is used interchangeably with the term “polymer”.

0034[0028] The term “includes” is synonymous with “comprises”. [0029] Referring to FIGS. 1-11, the present invention is directed to protected substrates and methods for protecting a substrate as described herein.

0035[0030] Referring to FIG. 1, a protected substrate 100 includes a substrate 112. The substrate 112 may be made of any suitable material, and may be a substrate manufactured at a manufacturing facility and shipped to a customer site, such that the substrate 112 is susceptible to damage during shipping. In some non- limiting examples, the substrate 112 may include glass. For example, the substrate 112 can comprise soda-lime glass, borosilicate glass, or leaded glass. In one non- limiting exemplary embodiment, the glass may include soda-lime glass. The glass can be clear glass. By “clear glass” is meant non-tinted or non-colored glass. Alternatively, the glass can be tinted or otherwise colored glass. The glass can be annealed or heat-treated glass. As used herein, the term “heat-treated” means tempered or at least partially tempered. The glass can be any type such as conventional float glass, and can be of any composition having any optical properties (e.g., any value of visible radiation transmittance, ultraviolet radiation transmittance, infrared radiation transmittance, and/or total solar energy transmittance). By “float glass” is meant glass formed by a conventional float process in which molten glass is deposited onto a molten metal bath and controllably cooled to form a float glass ribbon. In other non- limiting examples, the substrate 112 may include metal or wood. For example, the substrate 112 can comprise steel, copper, aluminum, or a combination thereof. The metal substrate may be a sheet or a bar. The substrate may be made of any material capable of being damaged (e.g., scratched, corroded, etc.) during shipping.

0036[0031] The substrate may be a coated substrate, having a functional coating layer over the bare substrate, such as coated glass. As used herein, the term “functional coating” refers to a coating which imparts a functional benefit to the surface beyond decoration of the surface. Non-limiting examples include coatings that impart an optical property, structural property, electrical property, hygienic property, thermal property, and/or physio-chemical property to the surface. Non-limiting examples of functional coatings include at least one of a low-e (low- emissivity) coating, a hydrophilic coating, a hydrophobic coating, an oleophilic coating, a low friction coating, an anti-microbial coating, an anti-fingerprint coating, an anti-fog coating, a self-cleaning coating, an easy-clean coating, a transparent conductive coating, and combinations thereof.

0037[0032] The functional coating layer may comprise a metallic layer comprising a metallic material, such as gold, copper, silver, aluminum, palladium, or a combination thereof. The functional coating layer may be applied to the substrate using magnetron sputtering vapor deposition (“MSVD”), such as a MSVD coated glass. Non-limiting examples of suitable functional coatings and coated substrates are disclosed in US 2017/0341977; US 2018/0118614; US 2019/0204480; US 7,335,421; US 8,865,325; US 9,932,267; and US 10,479,724; all of which are incorporated herein by reference in their entirety.

0038[0033] In some non-limiting embodiments, the substrate 112 may be a large substrate, such that multiple protective sheets are required to protect the entire surface of the substrate 112 during shipping. In some examples, the large substrates may have a length exceeding 100”, such as at least 130”, at least 160”, at least 190”, at least 220”, at least 250”. In some examples, the large substrates may have a width exceeding 100”, such as at least 130”, at least 160”, at least 190”, at least 220”, at least 250”. One non-limiting example of such a planar substrate includes a glass sheet.

0039[0034] In some non-limiting embodiments, the substrate 112 may be a planar substrate, such as a flat glass sheet. As used herein, a “planar substrate” refers to a flat substrate.

0040[0035] With continued reference to FIG. 1, the protected substrate 100 further includes a temporary protective layer 114 positioned over at least a portion of a surface of the substrate 112. The temporary protective layer 114 may be formed from a composition that, when applied to the surface of the substrate 112 and solidified, forms a layer thereover defined as the temporary protective layer 114. The temporary protective layer 114 may be positioned over at least a portion of a surface of the substrate 112, and in some non-limiting embodiments is positioned over at least the entire surface of the substrate 112. The temporary protective layer 114 may be applied over at least a portion of an edge of the substrate 112.

0041[0036] The temporary protective layer 114 may include a polyurethane layer, an epoxide layer, or a combination thereof. As used herein, a “polyurethane layer” is a layer that comprises urethane linkages and/or is made from components comprising a polyurethane. For example, the polyurethane layer may comprise urethane linkages. The temporary protective layer 114 may include an epoxide layer. As used herein, an “epoxide layer” is a layer that comprises an epoxide or that is obtained from components comprising an epoxide. For example, the epoxide layer may comprise epoxide groups.

0042[0037] The temporary protective layer 114 may include both a polyurethane layer and an epoxide layer. If both a polyurethane layer and an epoxide layer are present, the polyurethane layer and epoxide layer may be formed together such that the temporary protective layer 114 comprises one layer comprising both a polyurethane and an epoxide. Alternatively, if both a polyurethane layer and an epoxide layer are present, the polyurethane layer and epoxide layer may be formed as separate layers. For example, the polyurethane layer may be formed over the substrate and the epoxide layer may be formed over the polyurethane layer. As a further example, the epoxide layer may be formed over the substrate and the polyurethane layer may be formed over the epoxide layer.

0043[0038] The temporary protective layer 114 may be formed from a coating composition. The coating composition may comprise a polyurethane, an epoxide, or a combination thereof. [0039] The coating composition may comprise a polyurethane. Examples of polyurethanes include aqueous polyurethanes, polyurethanes formed from a two component system, emulsions thereof, and combinations thereof. The polyurethane may comprise additional functional groups including ester linkages, ether linkages, and hydrophilic groups such as hydroxyl groups, carboxyl groups, carbonyl groups, amino groups, thiols, and the like. Hydrophilic functional groups may be incorporated into the polyurethane to aid in the formation of an emulsion. The polyurethane may be a polyurethane polymer. For example, the coating composition may comprise an oil-modified polyurethane polymer.

0044[0040] The polyurethane may be obtained by reacting one or more hydroxyl functional compounds with one or more isocyanate functional compounds. The hydroxyl functional compounds can include diols and/or polyols having 3 or more hydroxyl functional groups. As used herein, a “polyol” refers to any compound that includes 2 or more hydroxyl groups.

0045[0041] The polyurethane polymer may be formed from a mixture of reactants. The mixture of reactants used to form the polyurethane polymer may comprise an oil polyol. If an oil polyol is used in the mixture of reactants used to form the polyurethane polymer, the polyurethane polymer may be considered an oil-modified polyurethane polymer.

The amine chain extender may comprise an amine value of up to 2,500 KOH/mg, or up to 2,300 KOH/mg, or up to 2,100 KOH/mg, or up to 1,900 KOH/mg. The amine chain extender may comprise an amine value in the range of from 1,000 KOH/mg to 2,500 KOH/mg, or in the range of from 1,100 KOH/mg to 2,300 KOH/mg, or in the range of from 1,200 KOH/mg to 2,100 KOH/mg, or in the range of from 1,300 KOH/mg to 1,900 KOH/mg.

0113[00120] The amine chain extender may comprise at least two amine groups. For example, the amine chain extender may comprise at least two amine groups, or at least three amine groups, or at least four amine groups, or at least 5 amine groups.

0114[00121] The amine chain extender may comprise up to 10 amine groups, or up to 8 amine groups, or up to 6 amine groups. For example, the amine chain extender may comprise 2 amine groups to 6 amine groups.

0115[00122] The polyurethane dispersion may include an amine functional chain extender in an amount of at least greater than 0 weight %, based on the total weight of the polyurethane dispersion. The polyurethane dispersion may include an amine functional chain extender in an amount of up to 5 weight %, or up to 3 weight %, or up to 2 weight %, or up to 1 weight %, based on the total weight of the polyurethane dispersion. The polyurethane dispersion may include an amine functional chain extender in an amount in the range of from greater than 0 weight % to 5 weight %, or in the range of from greater than 0 weight % to 3 weight %, or in the range of from greater than 0 weight % to 2 weight %, or in the range of from greater than 0 weight % to 1 weight %, based on the total weight of the polyurethane dispersion.

0116[00123] The amine chain extender may react stepwise to chain extend the polyurethane polymer of the polyurethane dispersion.

0117[00124] The polyurethane dispersion may comprise water. The polyurethane dispersion may comprise water in an amount of at least 50 weight %, or at least 53 weight % or at least 55 weight %, or at least 60 weight %, based on the total weight of the polyurethane dispersion. The polyurethane dispersion may comprise water in an amount of up to 80 weight %, or up to 75 weight %, or up to 70 weight %, or up to 65 weight %, based on the total weight of the polyurethane dispersion. The polyurethane dispersion may comprise water in an amount in the range of from 50 weight % to 80 weight%, or in the range of from 53 weight % to 75 weight %, or in the range of from 55 weight % to 70 weight %, or in the range of from 60 weight % to 65 weight %, based on the total weight of the polyurethane dispersion.

0118[00125] The polyurethane polymer/polyurethane dispersion may be formed according to a specific method. For example, the components used to form the oil polyol may be reacted simultaneously first, followed by reaction of the components used to form the polyurethane polymer simultaneously, and then finally stepwise chain extension of the polyurethane polymer in an aqueous medium. [00126] As previously described, the coating composition may comprise an epoxide. Examples of epoxides include epoxy functional polymeric materials, which is also known as a polyepoxide and which comprises two or more epoxy functional groups. The epoxide may be an emulsion. The epoxide can comprise one or more additional functional groups (e.g. carboxylic acid and/or hydroxyl functional groups) and be reactive with itself as a self- crosslinkable compound to form the reaction product. Alternatively, the epoxide can be reacted with a second compound such as a carboxylic acid and/or hydroxyl functional compound to form the reaction product. The epoxide layer may also comprise epoxy functional groups when there are excess epoxy functional groups in the reactants. Alternatively, the epoxy functional groups may all react during the reaction to form the reaction product such that no epoxy functional groups are present in the epoxide layer.

0119[00127] The coating composition may further include additional components such as, for example, a wax, an organic oil (e.g., tung oil), a polyolefin, a poly(meth)acrylate, a polyester, an alkene, a polyethylene, a polypropylene, an emulsion thereof, or some combination thereof. For instance the coating composition used to form the temporary protective layer 114 may further comprise polylactic acid (PLA), polyethylene carbonate (PEC), polypropylene carbonate (PPC), polycaprolactone, polyoxymethylene, polyethylene, polypropylene, or some combination thereof. The wax may include stearic acid, paraffin, camauba, microcrystalline wax, polyethylene wax, or some combination thereof. Examples of wax emulsions include those available from Michelman, Inc. (Cincinnati, OH) (e.g., MGRD 1350, ML160, ME62330, Aqua240 PH90602L, ME48040M2) or BYK-Chemie GmbH (Wesel, Germany) (e.g., AQUACER 526, AQUACER 541, AQUACER 1031, AQUACER 8500). The wax emulsion may be a paraffm/polyethylene emulsion, an anionic polyamide emulsion, an anionic camauba emulsion, an amine dispersed camauba emulsion, an ethylene acrylic acid emulsion, a non ionic microcrystalline emulsion, or some combination thereof. In some non-limiting examples, the temporary protective layer 114 may include an alkane, an ester, or a carboxylic acid and have at least 40 wt.% carbon, based on the total weight of the temporary protective layer, such as at least 50 wt.%, at least 60 wt.%, at least 70 wt.%, at least 80 wt.%, or at least 90 wt.%. [00128] The temporary protective layer 114 may include a material that when included in the coating composition and applied to a substrate and solidified to form the temporary protective layer 114, the layer exhibits a water contact angle (WCA) (upon contact with water) of at least 60°, such as at least 70°, or at least 80°. The temporary protective layer 114 may include a hydrophobic material. A hydrophobic material is defined herein as a material that when included in a composition and applied to a substrate and solidified to form a layer, the layer exhibits a WCA (upon contact with water) of at least 90°, such as at least 100°, at least 110°, at least 120°, at least 130°, at least 140°, or at least 150°.

0120[00129] The coating composition used to form the temporary protective layer 114 may be dispersed in an aqueous medium. As used herein, an “aqueous medium” refers to a liquid medium comprising greater than 50 weight % of water, based on the total weight of said liquid medium. For example, the coating composition may be dispersed in a liquid medium that comprises greater than 50 weight % of water, or at least 55 weight % of water, or at least 60 weight % of water, or at least 65 weight % of water, or at least 70 weight % of water, or at least 75 weight % of water, based on the total liquid weight of said medium. The coating composition may be dispersed in a liquid medium that comprises water in an amount of from 50 weight % to 80 weight %, or in the range of from 50 weight % to 75 weight %, or in the range of from 50 weight % to 70 weight %, or in the range of from 55 weight % to 70 weight %, or in the range of from 60 weight % to 70 weight %, or in the range of from 60 weight % to 65 weight %, based on the total liquid weight of said medium. As such, the liquid medium may comprise less than 50 weight % of a solvent, based on the total weight of said liquid medium. The coating composition may be dispersed in a liquid medium that comprises a solvent in an amount of from greater than 0 weight % to 50 weight %, or in the range of from 0.5 weight % to 25 weight %, or in the range of from 0.5 weight % to 15 weight %, or in the range of from 1 weight % to 10 weight %, or in the range of from 1 weight % to 5 weight %, based on the total liquid weight of said medium.

0121[00130] The coating composition used to form the temporary protective layer 114 may be free of a solvent, such as volatile organic compounds (“VOC”).

0122[00131] Non-limiting examples of solvents that may be used in the coating composition include glycols, alcohols, glycol ether alcohols, volatile ketones, glycol diethers, esters, amines, diesters, aromatic and aliphatic hydrocarbons, pyrrolidones such as n-methyl pyrrolidone, and combinations thereof.

0123[00132] The coating composition used to form the temporary protective layer 114 may comprise a one-component coating composition. As used herein, the terms “one-component” or “IK” refer to a coating composition wherein all of the coating components are combined and stored in a single container. Alternatively, the coating composition may comprise a two- component coating composition. As used herein, the terms “two-component” or “2K” refer to a coating composition wherein the components are stored separately and, when mixed with one another, react to crosslink to form a crosslinked material. For example, a polyurethane and/or an epoxide may be contained within a first container and a crosslinker may be contained within a second container. The temporary protective layer 114 may comprise a thermoset resin system of any of the previously mentioned materials of the temporary protective layer 114. As used herein, a “thermoset resin system” is a network of at least one crosslinked material that forms a layer.

0124[00133] The coating composition may comprise optional additional components. Non limiting examples of additional components include plasticizers, crosslinkers, viscosity modifiers, corrosion inhibitors, infrared (IR) absorbers, adhesion modifiers, UV absorbers, pigments, surfactants, and hydrophobic agents.

0125[00134] Non-limiting examples of suitable plasticizers for use in the coating composition of the temporary protective layer 114 include oils such as cotton seed oil, epoxidized soybean oil, and canola oil, waxes such as camauba wax, paraffin, and microcrystalline wax, polyethylene glycol, and polypropylene glycol. Plasticizers are included in the coating composition used to form the temporary protective layer 114 to aid in the removal of the temporary protective layer 114 via abrasion wheels, especially when the temporary protective layer 114 is a thermoset resin system. A plasticizer may be included in the coating composition used to form the temporary protective layer 114 in an amount in the range of 1 to 50 wt %, or 4 to 40 wt %, or 10 to 30 wt %, based on the total components of the coating composition used to form the temporary protective layer 114.

0126[00135] Examples of suitable viscosity modifiers include RHEOBYK-425, RHEOBYK-T 1000VF, RHEOBYK-L 1400 VF, and RHEOBYK-H 3300 VF commercially available from BYK and H1335 and HY124 commercially available from Spectrum. A viscosity modifier may be included in the coating composition used to form the temporary protective layer 114 in an amount in the range of 0.05 to 20 wt %, or 0.1 to 15 wt%, or 0.1 to 10 wt %, based on the total components of the coating composition used to form the temporary protective layer 114. [00136] Examples of suitable hydrophobic agents include waxes, oils, and fatty acids. A hydrophobic agent may be included in the temporary protective layer 114 in an amount in the range of 0.5 to 70 wt %, or 1 to 65 wt %, or 1 to 60 wt %, based on the total components of the coating composition used to form the temporary protective layer 114.

0127[00137] Examples of suitable crosslinkers for use in the coating composition of the temporary protective layer 114 composition include polyaziridines, polycarbodiimides, epoxy silanes, melamines, polyisocyanates, and combinations thereof. As used herein, a “crosslinker” refers to a compound that comprises two or more functional groups that are reactive with other functional groups and which is capable of linking two or more compounds through covalent bonds. [00138] The crosslinker may comprise a polyaziridine. The polyaziridine may be any compound that comprise two or more aziridine groups. One non-limiting example of a polyaziridine that may be used as a crosslinker in the temporary protective layer 114 is trimethylolpropane tris(2-methyl- 1 -aziridinepropionate).

0128[00139] The crosslinker may comprise a polycarbodiimide. The polycarbodiimide may be any compound that comprises

0129[00140] A crosslinker may be included in the coating composition of the temporary protective layer 114 in an amount in the range of 0.05 to 30 wt %, or 0.1 to 20 wt %, or 0.1 to 10 wt %, based on the total components of the coating composition used to form the temporary protective layer 114. Crosslinkers are included in the temporary protective layer 114 composition in order to crosslink the composition, such as to create a thermoset resin system. For example, the coating composition may comprise a crosslinker that is reactive with the functionality of the polyurethane polymer, and may comprise from 1 weight % to 5 weight %, or from 1 weight % to 3 weight %, or from 1 weight % to 2 weight %, based on the total weight of the wet polyurethane polymer. A stoichiometric ratio of reactive groups on the polyurethane polymer to the reactive groups on the crosslinker may be in the range of from 1:1 to 1:0.05, or in the range of from 1 :0.8 to 1 :0.1 , or in the range of from 1 :0.6 to 1 :0.2, or in the range of from 1:0.5 to 1:0.3.

0130[00141] The coating composition used to form the temporary protective layer 114 may comprise inorganic compounds, such as talc, silica, metallic catalysts, inorganic pigments, and the like. Alternatively, one or more of the coating layers (e.g. one or all of the coating layers) may be free of any of the previously described additional components, such as being free of inorganic compounds such as talc, silica, metallic catalysts, inorganic pigments, and the like. [00142] The coating composition used to form the temporary protective layer 114 may be a dual cure coating composition. As used herein, a “dual cure” coating composition refers to a coating composition that may use both light and chemical initiation to activate polymerization. If the coating composition used to form the temporary protective layer 114 comprises a dual cure coating composition, said dual cure coating composition may comprise one or more improved properties over a single, light or chemical cure coating composition. For example, a dual cure coating composition may result in a higher crosslinking density, improved chemical and water resistance properties, higher hardness, lower elongation properties, and higher tensile strength, compared to a single, light or chemical cure coating composition. In one non-limiting embodiment, the coating composition may comprise at least 2 crosslinkers, or at least 3 crosslinkers, or at least 4 crosslinkers. The at least 2 crosslinkers, or at least 3 crosslinkers, or at least 4 crosslinkers may be any of the crosslinkers previously described as suitable for use in the coating composition. The at least 2 crosslinkers, or at least 3 crosslinkers, or at least 4 crosslinkers may initiate polymerization and/or crosslinking with different mechanisms, such as light and chemical initiation. Alternatively, the coating composition may comprise at least one crosslinker and the polyurethane polymer may be self-crosslinking. For example, the coating composition may comprise at least one crosslinker and the polyurethane polymer may be self-crosslinking through oxidative cure.

0131[00143] The polyurethane polymer and/or polyurethane dispersion may be burnable. As such, if the polyurethane polymer and/or polyurethane dispersion is used in a coating composition, when said coating composition is cured to form a coating layer, said coating layer may be considered a burnable coating layer. The polyurethane polymer and/or polyurethane dispersion and any additional components discussed herein for use in a coating composition used to form the temporary protective layer, may be also used in a coating composition to form the first and/or second temporary protective sheets 116, 118, the temporary protective layer 214, the first and/or second temporary protective sheets 216, 218, the temporary protective layer 314, the first and/or second temporary protective sheets 316, 318, the first and or second temporary protective sheets 1016, 1018, the temporary protective layer 514, the first and/or second temporary protective sheets 516, 518, the temporary protective layer 1114, the burnable sheet 1128, the bum-off temporary protective layer 426, and/or the bum-off temporary protective layer 626. As such, the temporary protective layer 114, the first and/or second temporary protective sheets 116, 118, the temporary protective layer 214, the first and/or second temporary protective sheets 216, 218, the temporary protective layer 314, the first and/or second temporary protective sheets 316, 318, the first and or second temporary protective sheets 1016, 1018, the temporary protective layer 514, the first and/or second temporary protective sheets 516, 518, the temporary protective layer 1114, the burnable sheet 1128, the bum-off temporary protective layer 426, and/or the bum-off temporary protective layer 626 may be removable by burning, vaporizing, removing using a solvent, or peeling. For example, the temporary protective layer 114, the first and/or second temporary protective sheets 116, 118, the temporary protective layer 214, the first and/or second temporary protective sheets 216, 218, the temporary protective layer 314, the first and/or second temporary protective sheets 316, 318, the first and or second temporary protective sheets 1016, 1018, the temporary protective layer 514, the first and/or second temporary protective sheets 516, 518, the temporary protective layer 1114, the burnable sheet 1128, the bum-off temporary protective layer 426, and/or the bum-off temporary protective layer 626 may be removable by a heat treatment process that does not substantially damage the surface.

0132[00144] The temporary protective layer 114 may include a material having a melting point of at least 60°C, such as at least 70°C or at least 80°C. The temporary protective layer 114 may include a material having a melting point of up to 700°C, or up to 650°C, or up to 600°C. The temporary protective layer may have a melting point of from 60°C-700°C, or of from 60°C- 650°C, or of from 60°C-600°C, or of from 70°C-700°C, or of from 70°C-650°C, or of from 70°C-600°C, or of from 80°C-700°C, or of from 80°C-650°C, or of from 80°C-600°C. The temporary protective layer 114 may include a material that, when solidified, is impermeable to water and other standard processing liquids, such as cooling agents, cutting oils, and the like. The temporary protective layer 114 may provide increased corrosion protection to the substrate 112 compared to the same substrate not including the temporary protective layer 114 positioned thereover.

0133[00145] The material applied to form the temporary protective layer 114 may be a thermoplastic or thermoset. As used herein, a “thermoplastic” is a material that softens when heated and has a defined melting point. The material applied to form the temporary protective layer 114 may be a thermoset of any of the previously mentioned materials of the temporary protective layer 114. As used herein, a “thermoset” is any crosslinked material that does not have a defined melting point, and instead bums or decomposes when heated. The material applied to form the temporary protective layer 114 may have a low degree of cross-linking such that the material has a defined melting temperature. The material applied to form the temporary protective layer 114 may have a high degree of cross-linking such that the material does not have a defined melting temperature. A high degree of cross-linking can be achieved, for example, via solvent based formulations or by the addition of a crosslinker to an aqueous formulation.

0134[00146] In some non-limiting examples, the material applied to form the temporary protective layer 114 may include an emulsion comprising a hydrophobic material, water, and a surfactant, and the surfactant may be a non-ionic surfactant or an ionic surfactant (e.g., a cationic or an anionic surfactant). The material applied to form the temporary protective layer 114 may include a material comprising a hydrophobic material dissolved in a solvent. Alternatively, the material applied to form the temporary protective layer 114 may not be required to be dissolved in a solvent. The material applied to form the temporary protective layer may include an ultraviolet (“UV”) curable or heat curable material. As used herein, a “UV curable” material is a material that, when applied to a surface of a substrate and exposed to an UV source, results in crosslinking of the applied material on the substrate. As used herein, a “heat curable” material is a material that, when applied to a surface of a substrate and exposed to a heat source, results in crosslinking of the applied material on the substrate.

0135[00147] In some non-limiting examples, the material is heated until its temperature is at least the Tg of the material, and the material is applied at the temperature that is at least the Tg of the material. In other non-limiting examples the material is applied at a temperature below the Tg of the material and subsequently heated to a temperature suitable for the material to soften, such as above the Tg of the material. The material may also require a curing step at a temperature for a period of time. For example, the material may be cured at room temperature (i.e., in the range of 20-27°C, such as 25°C) for a period of time of up to 72 hours, or up to 48 hours, or up to 36 hours, or up to 24 hours. The material may also be cured at an elevated temperature, such as in the range of 90-180°C, or 100-170°C, or 110-150°C, or 120-130°C (such as 121°C), for a period of time of up to 2 hours, such as 1 hour, such as 30 minutes, such as 15 minutes.

0136[00148] The temporary protective layer 114 may be a layer removable from the surface of the substrate 112, even after the composition of the temporary protective 114 layer has been applied and solidified over the substrate 112 to form the temporary protective layer 114. The temporary protective layer 114 may be removed without substantially damaging the substrate 112 or rendering it unsuitable for its intended use (as hereinafter defined). The temporary protective layer 114 may be removed from the substrate 112 using any sufficient means, such as by burning, vaporizing, removing using a solvent, or peeling the temporary protective layer 114 from the substrate 112.

0137[00149] The temporary protective layer 114 may have a thickness ranging from lOnm to 5,000pm, such as lOnm to I,OOOmih, lOnm to 500pm, 0.5pm to lOOpm, 0.5pm to 10pm, lOpm to 30pm, or 50pm to lOOpm. The thickness should be sufficiently thick such that a continuous layer is formed. The temporary protective layer 114 may also be sufficiently thick so as to provide corrosion protection to the substrate 112. The temporary protective layer 114 may be thin enough such that upon burning, evaporating, or otherwise thermally decomposing of the temporary protective layer 114, substantial amounts of residue do not remain on the substrate 112. In this way, the temporary protective layer 114 may be burnable.

0138[00150] With continued reference to FIG. 1, the protected substrate 100 may further include a plurality of temporary protective sheets, including a first temporary protective sheet 116 and a second temporary protective sheet 118. The first temporary protective sheet 116 and the second temporary protective sheet 118 may be made of a plastic material, such as a polyethylene, polypropylene, polyester, polyethylene terephthalate, nylon, polyvinyl chloride, vinyl, polylactic acid, polyoxymethylene, or some combination thereof. The first temporary protective sheet 116 and/or the second temporary protective sheet 118 may comprise a thermoset resin system of any of the previously mentioned materials of the temporary protective sheet 116. In some non-limiting examples the second temporary protective sheet 118 may include a plastic film and a pressure sensitive adhesive applied on the plastic film. Examples of commercially available protective sheets include CGP-470, CGP-551, CGP-572, and/or CGP-591 protective films commercially available from Nitto Belgium NV (Genk, Belgium). The temporary protective sheets 116, 118 may include an adhesive layer that allows the temporary protective sheets 116, 118 to adhere to the layer over which they are placed. The adhesive layer may include a hydrophobic material exhibiting a water contact angle of at least 90°. In other examples, the temporary protective sheets 116, 118 do not include an adhesive layer and are positioned over the layer over which they are placed without adhering thereto using an adhesive.

0139[00151] The first and second temporary protective sheets 116, 118 may be positioned over the surface of the substrate 112. The first and/or second temporary protective sheets 116, 118 may be positioned over at least a portion of the temporary protective layer 114. The first and second temporary protective sheets 116, 118 may be separately formed plastic sheets positioned over the substrate 112. The temporary protective sheets 116, 118 may be positioned over the temporary protective layer 114 after the temporary protective layer 114 has been cooled to ambient temperature (after it has been solidified to form the temporary protective layer 114).

0140[00152] To form the protected substrate 100, the first and/or second temporary protective sheet 116, 118 may be positioned over the temporary protective layer 114 prior to shipping the protected substrate 100. Once the protected substrate 100 reaches its destination, the first and/or the second temporary protective sheets 116, 118 may be removed from the protected substrate 100, such that the removal (e.g., peeling or otherwise removing the sheets from the substrate) of the temporary protective sheets 116, 118 does not peel a majority (>50% by weight of the temporary protective layer 114) of the temporary protective layer 114 from the surface of the substrate 112. The removal of the first and/or second temporary protective sheets 116, 118 may leave substantially all (greater than 90% or greater than 95% by weight of the temporary protective layer 114) of the temporary protective layer 114 on the surface of the substrate 112. Thus, removal of the temporary protective sheets 116, 118 may leave the temporary protective layer 114 substantially intact over the surface of the substrate 112. [00153] The first and second temporary protective sheets 116, 118 may be positioned over the substrate 112 in any number of arrangements to form the protected substrate 100, and FIGS. 1-11 show various non- limiting embodiments of protected substrates 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1100 each of which is described in more detail hereinafter. It will be appreciated that components in FIGS. 1-11 having the same last two digits in their element number correspond to components from the other FIGS in the application and include the same characteristics of the corresponding components. For example, components 112, 212, 312, 412, 512, and the like all refer to the previously described substrate since all of these element numbers have the same last two digits (12).

0141[00154] Referring to FIG. 1, the temporary protective layer 114 is positioned over at least a portion of the surface of the substrate 112. The first and second temporary protective sheets 116, 118 are positioned over at least a portion of the surface of the substrate 112 and at least a portion of the temporary protective layer 114. The first and second temporary protective sheets 116, 118 overlap with each other to form an overlap portion. The first and/or second temporary protective sheets 116, 118 may be formed from a coating composition comprising any of the polymers and/or additives disclosed for use in a coating composition used to form the temporary protective layer 114. For example, the first and/or second temporary protective sheets 116, 118 may be formed from a coating composition comprising any of the coating compositions discussed herein that may be used as a coating composition used to form the temporary protective layer 114, including any of the materials and/or additives discussed herein; for example, the polyurethane polymer and/or polyurethane dispersion. In the example shown in FIG. 1, the temporary protective layer 114 is applied over an entire surface of the substrate 112, but in other non-limiting examples, the temporary protective layer 114 may be selectively applied over less than the entire substrate 112 (e.g., only over a section at an overlap of the temporary protective sheets 116, 118) ( see e.g., FIG. 7). Beneath the overlap portion formed by the first and second temporary protective sheets 116, 118, a gap 120 may be defined between the second temporary protective sheet 118 and a portion of the surface of the substrate 112. This gap 120 may be an air gap and may be free of material from the temporary protective layer 114, the first temporary protective sheet 116, and/or the second temporary protective sheet 118. In this way, the first and second temporary protective sheets 116, 118 are applied over the temporary protective layer 114, such that the gap 120 formed is free of material of the temporary protective layer 114, and the temporary protective layer 114, the first temporary protective sheet 116, and/or the second temporary protective sheet 118 does not fill the gap 120 between the first and second temporary protective sheet 116, 118. A portion of the temporary protective layer 114 is positioned between the second temporary protective sheet 118 and the portion of the surface of the substrate 112.

0142[00155] Referring to FIG. 10, the protected substrate 1000 may be identical to the protected substrates 100, 700 shown in FIGS. 1 and 7, respectively, except as follows.

It will be appreciated that any of the previously-described embodiments of protected substrates may include a coating layer (e.g., a functional coating layer) positioned between the substrate and the temporary protective layer.

0146[00160] The present invention is also directed to a method of protecting the previously- described substrates by forming the previously-described protected substrates.

0147[00161] In one non-limiting embodiment, the method for protecting a substrate may include: providing a substrate comprising a surface; applying a material to form a temporary protective layer over at least a first portion of the surface; adhering and/or positioning a first temporary protective sheet over a second portion of the surface, where a portion of the first temporary protective sheet overlaps a first portion of the temporary protective; and adhering and/or positioning a second temporary protective sheet over a second portion of the temporary protective layer and over a third portion of the surface. An overlap may be formed between the first temporary protective sheet and the second temporary protective sheet, and the gap may be defined by the overlap between the second temporary protective sheet and the surface.

0148[00162] In one non-limiting embodiment, the method for protecting a substrate may include: providing a planar substrate including a surface; applying a material to form a temporary protective layer over at least a first portion of the surface; adhering and/or positioning a first temporary protective sheet over a second portion of the surface; and adhering and/or positioning a second temporary protective sheet over a third portion of the surface where a space is formed between the first temporary protective sheet and the second temporary protective sheet. The space may be over the first portion of the surface, and the temporary protective layer may be positioned directly beneath the first and/or second protective sheet and positioned between the substrate and the first and/or second temporary protective sheet. [00163] The material applied to form the temporary protective layer may be applied over the surface of the substrate by any suitable method, such as spray coating, curtain coating, powder coating, brush coating, roll coating, inkjet printing, or some combination thereof. The temporary protective layer formed using any of these methods may include a polyurethane layer, an epoxide layer, or a combination thereof, which upon solidification forms the temporary protective layer. Examples of polyurethanes for the polyurethane layer include aqueous polyurethanes, polyurethanes formed from a two component system, emulsions thereof, and combinations thereof. Examples of epoxides for the epoxide layer include epoxy functional polymeric materials.

0149[00164] The method may include heating the material applied to form the temporary protective layer to a temperature sufficient to form a molten liquid prior to application of the material to the substrate. In some examples, this material may be applied to the surface of the substrate at a temperature above the melting point of the material. In some examples, the molten liquid may be applied to the surface of the substrate by bubbling a gas through the molten liquid (vapor deposition method) such that the material forms the temporary protective layer over the substrate. The gas bubbled through the molten liquid to deposit the material and to form the temporary protective layer may include an inert gas, such as nitrogen or helium. The inert gas may reduce the possibility of a chemical reaction with the material used to form the temporary protective layer. The material may further require a curing step at a temperature for a period of time. For example, the material may be cured at room temperature (i.e., in the range of 20- 27°C, such as 25°C) for a period of time of up to 72 hours, or up to 48 hours, or up to 36 hours, or up to 24 hours. The material may also be cured at an elevated temperature, such as in the range of 90-180°C, or 100-170°C, or 110-150°C, or 120-130°C (such as 121°C), for a period of time of up to 2 hours, such as 1 hour, such as 30 minutes, such as 15 minutes.

0150[00165] A method of removing a temporary protective layer from a coated substrate may include: providing a protected substrate, comprising: a planar substrate comprising a surface; a temporary protective layer positioned over at least a portion of the surface; a first temporary protective sheet positioned over at least a first portion of the surface; and a second temporary protective sheet positioned over at least a second portion the surface, wherein an overlapping portion of the second temporary protective sheet overlaps an overlapping portion of the first temporary protective sheet at an overlap, where a gap is defined by the overlap between the second temporary protective sheet and a portion of the surface and a portion of the temporary protective layer is positioned between the second temporary protective sheet and the portion of the surface. The method may include removing the first temporary protective sheet and/or the temporary protective sheet by peeling. The method may include removing the temporary protective layer from the surface by burning, vaporizing, removing using a solvent, or peeling the temporary protective layer to form an unprotected substrate. The protected substrate may be heated to a temperature of up to 1000°C to remove the temporary protective layer from the surface.

0151[00166] Referring to FIG. 11, the protected substrate 1100 may include the substrate 1112, a temporary protective layer 1114 positioned over at least a portion of the surface of the substrate 1112, and a burnable sheet 1128 positioned over at least a portion of the temporary protective layer 1114, and optionally in direct contact with the temporary protective layer 1114. The temporary protective layer 1114 and/or the burnable sheet 1128 may be formed from a coating composition comprising any of the polymers and/or additives disclosed for use in a coating composition used to form the temporary protective layer 114. For example, the temporary protective layer 1114 and/or the burnable sheet 1128 may be formed from a coating composition comprising any of the coating compositions discussed herein that may be used as a coating composition used to form the temporary protective layer 114, including any of the materials and/or additives discussed herein; for example, the polyurethane polymer and/or polyurethane dispersion. The burnable sheet 1128 may include polyethylene, polypropylene, polyacrylate, polymethyl methacrylate, polylactic acid, polycaprolactone, polyoxymethylene, or a combination thereof. The burnable sheet 1128 may optionally include an adhesive. The burnable sheet 1128 may be made of a material that allows at least some of the UV light to pass through it so as to cure the temporary protective layer 1114 arranged thereunder. UV radiation may be applied to the protected substrate 1100 using a UV source, and the UV radiation may cure the temporary protective layer 1114, which may also function as an adhesive to adhere the burnable sheet 1128 to the substrate 1112. The temporary protective layer 1114 and/or the burnable sheet 1128 may comprise any of the polymers and/or additives disclosed for use in the temporary protective layer 114. For example, the temporary protective layer 1114 and/or the burnable sheet 1128 may comprise any of the coating compositions discussed herein that may be used for the temporary protective layer 114, including any of the materials and/or additives discussed herein; for example, the polyurethane polymer and/or polyurethane dispersion. Both the temporary protective layer 1114 and the burnable sheet 1128 may bum away during a tempering process. The temporary protective layer 1114 may have the previously-described thickness. The burnable sheet 1128 may have a thickness of 0.1-10 mils, such as 0.5-5 mils or 0.5-2 mils. The burnable sheet 1128 may be an outermost sheet over the substrate 1112. The temporary protective layer 1114 and the burnable sheet 1128 may be made of a burnable material. The protected substrate 1100 may include a coating layer 1124, as previously described.

0152[00167] As used in this disclosure, the term “burnable” refers to a material that will bum, evaporate, or otherwise thermally decompose from the substrate, without interacting with the substrate or otherwise substantially damaging (as defined hereinafter) the aesthetics or performance of the substrate (including any coating thereover). Burnable materials would bum, evaporate or otherwise thermally decompose at least when the temperature of the substrate is from 500°C to 1000°C. It is anticipated that the burnable material will bum, evaporate, or otherwise thermally decompose before the substrate reaches a temperature of 1000°C, such as a temperature of 900°C, 800°C, 700°C, 650°C or 600°C. The heat treatment process may be conducted in a furnace having a temperature of up to 1200°C, such as up to 1100°C, up to 1000°C, up to 900°C, up to 800°C, up to 700°C, or up to 650°C. The furnace may operate at a temperature of 700°C, such that the substrate reaches a temperature of 640°C for the bum-off temporary protective layer (described hereinafter) to be removed during the heat treatment process. In some non-limiting embodiments, the burnable material may be removed during standard heat treatment processes, such as tempering, heat strengthening, or bending or during a heat treatment specifically performed to remove the burnable material without adversely affecting the substrate, as previously described. In some non-limiting examples, the burnable material may be removed during a standard tempering procedure in which the tempering ovens operate in the range of 500°C-1000°C, such as 600°C-800°C, or such a 650°C-750°C. [00168] Referring to FIG. 4, the protected substrate 400 may include the substrate 412 and a bum-off temporary protective layer 426 positioned over at least a portion of the surface of the substrate 412. The bum-off temporary protective layer 426 may be formed from a coating composition comprising any of the polymers and/or additives disclosed for use in the temporary protective layer 114. For example, the bum-off temporary protective layer 426 may be formed from a coating composition comprising any of the coating compositions discussed herein that may be used for the temporary protective layer 114, including any of the materials and/or additives discussed herein; for example, the polyurethane polymer and/or polyurethane dispersion. Referring to FIG. 6, the protected substrate 600 may include the substrate 612 and the bum-off temporary protective layer 626 positioned over at least a portion of the surface of the substrate 612 (like in FIG. 4), and may further include coating layer 624 between the substrate 612 and the bum-off temporary protective layer 626. The bum-off temporary protective layer 626 may be formed from a coating composition comprising any of the polymers and/or additives disclosed for use in the temporary protective layer 114. For example, the bum-off temporary protective layer 626 may be formed from a coating composition comprising any of the coating compositions discussed herein that may be used for the temporary protective layer 114, including any of the materials and/or additives discussed herein; for example, the polyurethane polymer and/or polyurethane dispersion. As used herein, the term “bum-off temporary protective layer” means a layer that is removable by a heat treatment process that does not substantially damage the surface. The bum-off temporary protective layer 426 and bum-off temporary protective layer 626 may be identical to or comprise the same components or similar components to the temporary protective layer 114 of FIG. 1.

0153[00169] The bum-off temporary protective layer 626 may comprise any of the polymers and/or additives disclosed for use in the temporary protective layer 114. For example, the bum- off temporary protective layer 626 may comprise any of the coating compositions discussed herein that may be used for the temporary protective layer 114, including any of the materials and/or additives discussed herein; for example, the polyurethane polymer and/or polyurethane dispersion.

0154[00170] The bum-off temporary protective layer 626 may have a thickness of lOnm to 5000pm, such as 1 p to 100pm, such as 5 pm to 50pm, such as from 5pm to 20pm. The bum- off temporary protective layer 626 may be an outermost layer over the substrate 612.

0155[00171] The bum-off temporary protective layer 626 may be removed by burning (or other heat treatment process) without substantially damaging the surface. As used herein, “substantially damaging” is defined as a change that is detrimental to the function or aesthetics of the substrate that constitutes any unwanted change in a substrate property that would make the substrate unacceptable for its intended purpose. For example, substantially damaging the surface may include substantial discoloration to the surface from the heat treatment process. In other applications where a heating step is part of the standard procedure, the damage may be defined as an unwanted color change due to the presence of burn-off coating as compared to a similar sample that is heated without the bum-off coating. As used here, substantial discoloration means a color change (DECMC) of more than 3 units, more than 2 units, or more than 1 unit compared to the color of an identical substrate processed without the bum-of coating subject to the same heat treatment process. DECMC (CIELAB) may be measured using an integrating sphere with D65 Illumination, 10° observer with specular component included according to ASTM Designation: D 2244 - 05 unless otherwise stated. Other examples of substantial damage include or could be induced by a change in surface roughness, a change in the oxidation state of the surface, or a change in surface energy due to the presence of bum-off coating during the heat treatment process, or an unwanted reaction between the bum-off temporary protective layer and the substrate during the heat treatment process. Substantial damage may include any detrimental change to a functional coating disposed over the substrate beneath the bum-off temporary protective layer (e.g., an anti-microbial functional coating that no longer sanitizes the surface after the heat treatment process, a hydrophobic functional coating that loses its hydrophobicity after the heat treatment process, a color change to the functional coating discemable by the human eye (e.g., DECM03, 2, or 1) compared to an identical substrate exposed to the same heat treatment process without the bum-off temporary protective layer.

0156[00172] The bum-off temporary protective layer 626 may be removable by burning at a temperature of up to 1000°C, such as up to 900°C, up to 800°C, up to 700°C, up to 600°C, or up to 500°C. The bum-off temporary protective layer 626 may be removed during standard heat treatment processes, such as tempering, heat strengthening, or bending or during a heat treatment specifically performed to remove the burnable material without substantially damaging the substrate 612. In one non-limiting examples, the burnable material may be removed during a standard tempering procedure in which the tempering furnaces operate in the range of 500°C-1000°C. The protected substrate 600 may include an optional coating layer 624, as previously described. [00173] With continued reference to FIGS. 4 and 6, the substrate may not include any temporary protective sheet over a surface of the substrate, as the bum-off temporary protective layer may sufficiently protect the substrate as the outermost layer.

0157[00174] In some non-limiting examples, the bum-off temporary protective layer may be positioned over the entire surface of the substrate. The bum-off temporary protective layer may also cover at least a portion of the edge of the substrate.

0158[00175] A method for protecting the substrate may include: providing the planar substrate comprising a surface and applying a material to form the bum-off temporary protective layer over at least a first portion of the surface. The bum-off temporary protective layer may be applied over the substrate using any of the previously describe methods of applying the temporary protective layer. The method may further include preparing the material via an emulsion, where the material is dispersed in water or an aqueous medium. As used herein, an “aqueous medium” is a liquid mixture comprising greater than 50 % water. Additional additives, such as crosslinkers, may be added during preparation of the material that forms the bum-off protective layer. Alternatively, the additional additives may be added right before the material is applied to form the bum-off temporary protective layer. The material may also require a curing step at a temperature for a period of time. For example, the material may be cured at room temperature (i.e., in the range of 20-27°C, such as 25°C) for a period of time of up to 72 hours, or up to 48 hours, or up to 36 hours, or up to 24 hours. The material may also be cured at an elevated temperature, such as in the range of 90-180°C, or 100-170°C, or 110- 150°C, or 120-130°C, for a period of time of up to 2 hours, such as 1 hour, such as 30 minutes, such as 15 minutes.

0159[00176] A method of removing a bum-off temporary protective layer from a coated substrate, may include: providing a coated substrate comprising a surface over a portion of which a bum-off temporary protective layer is applied and removing the bum-off temporary protective layer from the surface by burning the bum-off temporary protective layer to form an unprotected substrate. The coated substrate may be heated to a temperature of up to 1000°C to remove the bum-off temporary protective layer from the surface.
