Background of the invention

Certain representative embodiments of this invention relate to a coated product including a glass substrate supporting a low-E coating, wherein the low-E coating includes at least one absorbent layer to control the color and/or reflectivity of the coated article. . The coated product may be used in insulating glass (IG) window units in certain representative embodiments.

Coated products are popular in the industry for use in window applications such as insulating glass (IG) window units, automobile windows and/or the like. It is known that in certain examples, heat treatment (i.e., thermally temper, heat bending, and/or heat strengthening) of coated products may be desirable for tempering, bending, or tempering purposes. or something like that.

Insulating glass windows are well known in the industry. Conventional IG window units include at least two first and second glass substrates (one of which may have a solar control coating on an interior surface thereof) that are coupled to each other via a seal(s). s) or at least one spacer(s) washer(s). The gap formed between the two glass substrates may or may not be filled with a gas and/or evacuated to a low pressure in various examples. Some window units are tempered (IG). Thermally tempering the glass substrates with these IG units typically requires heating the glass substrates to a temperature(s) of at least 580°C for a sufficient period of time to cause thermally tempering. Architectural single windows intended for use in homes or buildings are also known in the industry and may include a coating supported by a glass substrate. Windows installed in homes can be made of glass panels. These monolithic windows can also be optionally thermally tempered for safety purposes. Heat treatment (i.e., heat hardening) of coated products typically requires a temperature(s) of at least 580°C, preferably at least 600°C and more preferably at least 620°C.

In certain circumstances, designers of coated products often struggle to find a combination of desired visible transmission, coloration, low reflectance, low emissivity, and low sheet resistance (Rs) sheet resistance. The low emissivity properties and low film resistance allow such coated products to block large amounts of infrared radiation and thus reduce, for example, unwanted heating in the interiors of cars or buildings. Designers of coated products also strive for specific color themes (i.e., when viewed from the outside of a building or vehicle on which the coated product has been installed) and/or achieving a low visible reflectance coefficient. Typically, thick infrared reflective layers (i.e., silver based layers), when they block infrared rays, cause a higher visible reflectance value. Thus, in the past it has been considered difficult to achieve a combination of good infrared blocking and at the same time a low or relatively low visible reflectance coefficient.

In light of the above, it will be obvious to those with experience in the field that there is a need in the field to manufacture a coated product that has one or more properties including desirable visible transmission, desirable color values, low reflectance values, low emissivity, And/or low sheet resistance (Rs). In certain representative embodiments, it will be evident that there is an industry need to manufacture a coated product (i.e., for use in an IG window unit) that can achieve a combination of the desired color (i.e., a* and/or b* values), and low visible reflection coefficient values Completely low visible reflectance, low emissivity, and/or low sheet resistance, and visible transmission are desirable.

The color of the side (or outside) of the glass (i.e., a*g and/or b*g values) may be optimized depending on the thickness and material/composition of the individual layers of the low-E coating in certain representative embodiments, which is What is considered distinctive in terms of aesthetic and architectural perspectives. Additionally, good solar properties (i.e., low sheet resistance and acceptable visible transmission) can be achieved in certain representative examples of coatings disclosed herein.

Detailed description

Products coated according to representative embodiments of this invention may be used in applications such as IG window units, vehicle windows, single architectural windows, residential building windows, and/or any other suitable application involving a glass substrate. Single or multiple. Similar reference numbers in different figures refer to similar parts/layers in this application.

Sheet resistance (Rs) shows emissivity or emissivity. The low laminar resistance in certain representative embodiments of this invention is achieved, in combination with the desired color tone and reflection coefficient values, as a result of the presence of the absorbing layer(s). In certain representative embodiments of this invention, a coated product achieves a film resistance of not more than 10 ohms/square, more preferably not more than 9 ohms/square, more preferably not more than 5 ohms/square, and more preferably not more than 4 ohms. /square, and potentially or most preferably less than or equal to 3.5 ohms/square. Such film resistance values, applicable to any embodiment of this invention, may be prior to and/or after optimal heat treatment such as thermally tempering of the coated product. In certain representative embodiments, the film resistance can be no more than 3 ohms/sq. Low sheet resistance (Rs) shows low emissivity.

In certain representative embodiments of this invention, the low-E coating includes a single infrared reflective layer comprising silver and/or gold, although this invention is not limited to that in all examples. While it may sometimes be possible to provide a number of other IR reflective layers, it is preferable to use one in certain examples because lower emissivity can be achieved and this many layers are not required, making the coating easier to manufacture, less costly to manufacture, and less susceptible to yield problems.

In certain representative embodiments of this invention (i.e., see Figures 1-5), the coated products may not be heat treated (i.e., thermally tempered). In certain representative embodiments of this invention (i.e., see Figures 1-5), the coated products can have an emissivity (regular and/or semicircular) of no more than 0.12, 0.11, and/or 0.10, and preferably no More than 0.06, more preferably no more than 0.05, and more preferably no more than 0.04 (i.e., 0.037). In certain representative embodiments, after heat treated as measured in a single image, the coated products (i.e., see Figures 1-5) before and/or after heat treated achieve visible transmission (III.C, 2 marks) is 60%, more preferably 50%, and more preferably not more than 45% or 40%. In representative embodiments, the coated product has a visible transmittance of 20-50%, more preferably 30-48%, in mono and/or IG form.

The solar factor (solar factor, or g-value), calculated according to the EN 410 standard, relates to the ratio between the total energy entering a room or the like through the glass panels and the incident solar energy. Therefore, it will be realized that low solar factor values show good solar protection against unwanted heating of rooms or the like protected by windows/glass panels. For example, a low solar factor value for a coated product (i.e., an IG unit such as double or triple glazing) indicates the ability to maintain a completely cool room in the summer months while hot ambient conditions exist.

While low solar factor values are typically desirable for coated products such as IG window units, achieving low solar factor values usually comes at the expense of visible transmission and/or coloration. It is often desirable, but difficult, to achieve a combination of acceptable visual transmittance properties, acceptable glazing coloration values, and a low solar factor value for a coated product such as an IG window unit or similar. In this regard, the ratio between visible transmittance (Tvis) and solar factor is sometimes referred to as “selectivity”. In other words, the “selectivity” of a Tvis/solar coated product is determined. High selectivity values are often desirable, because this combines the high or desired visible transmittance with a low solar factor value that indicates good infrared blocking.

In certain representative embodiments of this invention, a coated product is provided with a layer stack that may allow the coated product to achieve one or more characteristics of good Tvis selectivity, acceptable solar factor, and/or low emissivity. One, two, three, or all of those features may be realized in various embodiments of this invention (i.e., see Figures 1-5). When good Tvis/selectivity is achieved, a high ratio of visible transmission (Tvis) to solar factor is provided, which those experienced in the field may appreciate.

In certain representative embodiments of this invention (i.e., see Figures 1-5), a coated product such as an IG window unit achieves a selectivity value, Tvis/solar factor, of at least 1.12 or 1.20, preferably at least 1.30, and more preferably 1.35. At least, and in certain examples at least 1.40 or 1.43. In certain representative embodiments of this invention, good selectivity is achieved without sacrificing solar factor values. In other words, good selectivity values are achieved along with other low solar factor values. In certain representative embodiments of this invention, the coated products achieve good selectivity values, along with a solar factor value not exceeding 31, more preferably a solar factor value not exceeding 30, more preferably a solar factor value not exceeding 29, and more preferably a solar factor value not exceeding 30. Solar no more than 28. This allows coated products and/or IG window units, for example, to achieve desirable visible transmission while at the same time blocking noticeable unwanted radiation (i.e., infrared radiation (IR)) reaching the interior of the building or Similar.

In certain representative embodiments of this invention, coated products having a single infrared reflective layer are capable of having a low glass side reflection coefficient. In certain representative embodiments, before and/or after heat treatment, the coated product such as IG window units according to certain representative embodiments of this invention has a visible reflectance coefficient of the glass side (Y) of not more than 16%, preferably 15% or Less, preferably more 14% or less, while maintaining a desired color.

The terms “heat treated” and “heat treated” as used herein mean heating the product to a temperature sufficient to obtain thermal tempering, heat bending, and/or thermal strengthening of the product containing glass. This definition includes, for example, heating the coated product in an oven or kiln at a temperature of at least 580°C, preferably at least 600°C, for a period sufficient to permit tempering, bending and/or thermal strengthening. In certain examples heat treatment (HT) can extend 4 or 5 minutes. The coated product and/or IG unit may be heat treated or non-heat treated in various embodiments of this invention.

Figure 1 is a cross-sectional projection of the coated product according to a non-specific representative embodiment of this invention. The coated product comprises a substrate 1 (for example, a substrate of clear, green, bronze or blue-green glass, between 1 and 10 mm thick, and a low emissivity coating (or layering system) 30 applied to the substrate 1 either directly Or indirectly. The coating (or layer system) 30 includes, for example, an insulating substrate 3 which may be silicon nitride (i.e., SixNy and/or Si3N4), silicon oxide and/or silicon oxynitride in various embodiments thereof. of the invention, a highly colored and/or reflectively controlled metallic or metallic absorber/separator layer 4 (i.e., comprising one or more Ni, Cr, NiCr, Nb, Zr, and /or NbZr, and/or Si, and/or Ti, and/or Zn, and/or Sn, and/or Cu, and/or Al, and/or V, and/or Mn, and/or Mo, and /or Pd, and/or Ta, and/or W, and/or In, and/or InSn, and/or Stainless steel, and/or an alloy thereof; The foregoing materials may be partially and/or fully oxided and/or nitrided), and the insulating layer 5 may be of or comprising silicon nitride (i.e., SixNy and/or Si3N4), and/or of silicon oxide and/or of silicon oxynitride in various embodiments of this invention (which may be substantially similar to or of the same material and/or composition as layer 3 in certain embodiments), and a first bottom contact layer 6 (which contacts the bottom IR reflective layer reflecting layer 7), an infrared (IR) reflecting layer that is conductive and preferably metallic or largely metallic 7, an upper contact layer 8, an insulating layer 9, and a color-controlling absorbent layer and/or reflectometer 10 (i.e., including one or more Materials Ni, and/or Cr, and/or NiCr, and/or Nb, and/or Zr, and/or NbZr, and/or Si, and/or Ti, and/or Zn, and/or Sn, and/ or Cu, and/or Al, and/or V, and/or Mn, and/or Mo, and/or Pd, and/or Ta, and/or W, and/or In, and/or InSn, and/or or stainless steel, and/or an alloy thereof; the foregoing materials may be oxidized and/or treated partially and/or fully nitrided), an insulating layer 11, and a topcoat layer 12. The dielectric layers 3 and 5, and the layers 9 and 11, may be of the same material and/or composition in certain representative embodiments, such that the dielectric layers are divided by an absorbing layer Overlapping. It is noted that all of the preceding coatings may or may not be included in low-E coating 30 in certain representative embodiments. Specifically, only one of the color and/or reflectance-control absorbing layers 4, 10 may be present in some embodiments (i.e., see Figures 3(a) and 3(b), or both may be present (i.e., see Figures 1, 4) c), and 5 (c)). Each of the “contact” layers 6 and 8 is in contact with the infrared reflective layer 7 (i.e., an Ag-based layer that compensates for the previous layers 3-12 (i.e., low-emissivity) coating 30 which is made Provided on a glass or plastic substrate 1. Additional layers can also be provided.

In single type examples, the coated product includes a single glass substrate 1 as shown in Figure 1. However, single coated products in this application may be used in devices such as laminated automotive glass panels, IG window units, And so on.

Figure 2 is a cross-sectional view of a glass IG unit, showing that the coating 30 can be provided on the inner side of the glass substrate 1. However, the invention is not limited to this, and it is noted that the coating 30 can be provided On any of the glass substrates, preferably on the substrate close to the gap 17.

As Figure 2 describes, an IG window unit can include two glass substrates spaced 1 and 50 apart. A representative IG window module is illustrated and described, for example, in US Patent No. 2004/0005467, the contents of which are incorporated herein by reference. A representative IG window unit may include, for example, the coated glass substrate 40 shown in Figure 1 (or any of Figures 3-5) coupled to another glass substrate 50 via spacer(s) washer(s), material ( sealant(s) or the like (15), with a gap 17 defined between them. In some examples this gap 17 between pillars in IG unit models can be filled with a gas such as argon (Ar). A representative IG unit may comprise a pair of two transparent glass substrates spaced 3-4 mm thick each, one of which is coated with low-E coating 30 in certain representative cases of this application, where the gap between the substrates is from 5 to 30 mm, preferably 10 to 20 mm, more preferably 16. In certain representative embodiments, the coating 30 is provided on the inside of the glass substrate (i.e., closest to the outside) maximum 1 as shown in Fig. 2. However, in other embodiments, coating 30 may be provided on the inner surface of any substrate facing the gap. The IG unit may also include additional substrate(s), such as three glass substrates, in certain cases.

Figures 3-5 illustrate in other representative embodiments of this invention, the proposed coating therein may be used in connection with Figures 1 and/or 2.

Notably, it has been discovered that the aforementioned layer stack (i.e., see Figures 1-5) includes a color and/or reflectivity-adjusting absorber layer (4 and/or 10) with thicknesses of Variation in one or multiple positions results in desirable optical properties. More specifically, in certain representative embodiments, by adjusting the thickness of the color-adjusting and/or reflectivity-adjusting absorbent layer(s) 4 and/or 10, the coloration of the glass side of the coated product (a*g and/or b* values) can be converted g for the side of the glass) so that it appears as a specific color when the window unit is viewed from the outside. The absorbent layer(s) 4 and/or 10 can be conductive in certain representative cases. The values of a*g and/or b*g in this application refer to the reflective color values of the side of the glass, as viewed from the glass side of a monolithic coated article or from the side of an IG window unit configured to face the outside of a building or structure, unless otherwise stated. that. Similarly, the visible reflectance coefficient (Y) refers to the visible reflectance of the side of the glass, as seen from the glass side of a single-coated product or from the side of an IG window unit configured to face the outside of a building or structure.

More specifically, in certain representative embodiments, embedding an absorbent layer 4 between barrier layers 3 and 5 can cause a coated product to have desirable optical properties. In certain representative embodiments, insulating layers 3 and 5 have substantially similar materials/composition. Essentially, in certain representative embodiments, a silicon-based layer is divided into two layers, 3 and 5, and a color and/or reflectivity-adjusting absorber layer is provided between the two dielectric layers. Layers 3 and 5 can have different thicknesses in certain representative models. In other embodiments, layers 3 and 5 may have the same thickness. The thickness of layers 3 and 5 can be varied to contribute to achieving a desired side glass color (desired a*g and/or b*g values for the side glass). The “desired” side color of the glass can vary in certain cases.

In certain representative embodiments , the color of the glass side of the coated product (a* and b* for the glass side) can be bronze, green, clear, or blue. Thus, coating 30 may be applied to a transparent glass substrate 1, and the coated product (single, or when measured as an IG unit) will have a colored appearance while still retaining its desired characteristics as those of a low-E coating, such as no increased film resistance (Rs) sheet resistance Not more than 10 ohms/square, or 9.5 ohms/square, or 9 ohms/square, preferably not more than 5 ohms/square, more preferably not more than 4 ohms/square, most preferably less More than or equal to 3.5 ohms/square before and/or after treatment The optimal heat treatment, such as tempering, has an emissivity of less than 0.12, 0.11, and/or 0.11, preferably less than 0.06, more preferably less than 0.05, and more preferably less than 0.04 (i.e., 0.037). The resulting coated product can have a low glazing side (or building exterior) reflection coefficient (Y) of 16% or less, and preferably 14% or less (i.e., unit IG), in certain representative embodiments, depending in part on the color desired.

In certain exemplary embodiments, depending in part on the material chosen for the absorbent layer(s) 4 and/or 10, and the thickness and material values of the layers 3-12, a coating prepared in accordance with certain exemplary embodiments may be provided on a transparent glass substrate, giving The glass substrate has a desirable color profile (e.g., bronze colored). For example, coating 30 can result in a coated product that, when viewed from the side of the glass (outside the building in Figure 2), in certain representative embodiments, has a bronze, clear, green, royal blue, and/or tint of Other colors are made from combinations of them.

The absorbent layer(s) are advantageous because the reflectivity of the side and/or outside of the glass is reduced, and the desired visible transmission, color, and low solar factor can be achieved, without sacrificing laminate resistance. For example, without limitation, it is often artistically pleasing for a structure such as any building to have windows with low side-glass reflectivity. Architects may therefore prefer to have a reduced visible reflectance of the side (or outside) of the glass, but will not risk sacrificing laminate strength, color and/or visible transmittance for this purpose. In certain representative embodiments, the thickness of the infrared reflective layer(s) 7 may be increased, which may include silver or gold. Increasing the thickness of the layer 7 may increase the reflectivity value of the glass side, and therefore, if the value of the glass side reflectivity is reduced by the inclusion of absorbing layer(s) 4 and/or 10, but increased by a thicker layer 7, the net change in the reflectivity of the glass side may be Glass is minimal, equal to zero, or very close to zero. Increasing the thickness of the IR reflective layer 7 is desirable because it enhances the IG module's ability to block/reflect infrared radiation, which may reduce the amount of infrared radiation entering a building, structure, vehicle, etc., through the window.

In certain representative embodiments, layers 3-12 are sprayed onto a glass substrate. This can apply to any of Figures 1-5. The spray target(s) may be in planar form or on rotating cylindrical magnetron spray targets (not shown) in representative embodiments of this invention. Metal and/or ceramic targets may be used.

Of which. The thickness of Layer 4 can range from 10 to 150 angstroms in certain representative embodiments, preferably from 20 to 70 angstroms. However, in other embodiments, layer 4 can be thicker, sometimes significantly, than 150 angstroms.

Continuing with reference to Figures 1-5, contact layers 6 and 8 may include Ni, Cr, and/or NiCr materials, or oxides thereof, in certain exemplary embodiments. Other suitable materials may be employed instead or used as well. Contact layers 6 and 8 may be partially and/or completely oxided and/or nitrided in certain representative cases. In certain embodiments, contact layers 6 and 8 can help prevent the infrared reflective layer 7 from becoming an oxidized layer during application of other layers and/or during heat treatment. It is possible to use other materials in alternative models. The thickness of each of the contact layers 6 and 8 can range from 10 to 150 angstroms in certain embodiments, preferably from 10 to 60 angstroms.

Continuing the reference to Figures 1-5, the insulating layers 9 and 11 may comprise or consist primarily of silicon oxide, and in other representative embodiments, they may comprise or consist primarily of silicon oxide, and/or silicon oxynitride. Insulating layers 9 and 11 may be partially and/or completely oxided and/or nitrided. In certain representative embodiments, the insulating layers 9 and 11 may have the same or substantially similar materials and/or composition. It is noted that each of the silicon nitride, silicon oxynitride, and/or silicon oxide layers herein (i.e., see Figures 3, 5, 9, and/or 11) may be distorted in a way Optional aluminum (i.e., 1-5%), stainless steel, or similar. In certain embodiments, the thickness of layers 9 and 11 may be the same or substantially the same. The thickness of each of layers 9 and 11 may range from 70 to 1200 angstroms in certain representative embodiments. In certain representative embodiments, only one of layers 9 and 11 may be present; However, in other embodiments, both layers may be provided.

Layer 10 may be a color and/or reflectivity-adjusting absorber layer in certain representative embodiments (i.e., see Figures 1-5). For absorbent layers 4 and 10, the layer stack may include layers 4 and 10, layer 4 only, or layer 10 only. Layer 10 may be of or comprise any of the following materials, or a mixture (alloy) of any of these materials: Ni, and/or Cr, and/or NiCr, and/or Nb, and/or Zr, and/or NbZr, and/or Si, and/or Ti, and/or Zn, and/or Sn, and/or Cu, and/or Al, and/or V, and/or Mn, and/or Mo, and/or Pd, Ta, W, In, InSn, and/or stainless steel.

The thickness of layer 10 can range from 10 to 150 angstroms in certain representative models. However, in other embodiments, layer 10 can be thicker than 150 angstroms. Certain models may not include layer 10, may have it instead of layer 4, or both layers may be present.

12 coat topcoat is optional. The layer 12 may be provided over the infrared reflective layer 7 and over the insulating layer(s) 9, 11. Layer 12 may include oxide, nitride, zirconium oxynitride and/or aluminum (i.e., ZrOx, ZrOxNy and/or A10xNy) in certain representative embodiments of this invention.

The coated product made in accordance with the above embodiments (i.e., see Figures 1-5) may be used in an IG unit (i.e., see Figure 2). The IG unit may or may not be a vacuum IG unit. In other representative embodiments, the coated product may be used as a single window unit.

A coated product and/or IG unit manufactured in accordance with the above embodiments has the advantage of reducing the reflectivity of the glass side due to the absorption properties of the absorbent layer(s) controlling the color and/or reflectivity. In certain representative embodiments, good selectivity may be achieved at a given glass side reflectivity value by increasing the thickness of the infrared reflective layer (i.e., silver based layers)7. A coated product and/or IG unit may also be made according to certain embodiments of this invention for improved thermal, mechanical, and chemical tolerance compared to split-silver reflective coatings.

Coated products with neutral, green, blue, bronze, gold, etc. colors can be achieved. It has been discovered that coated products and/or IG units made according to certain embodiments of this invention can have a reduced reflectivity of the glass side (or outside) of a “split silver” (or double silver) coating with color variation of a coated product containing an infra-reflective layer. Single IR reflecting layer.

In certain exemplary embodiments, the reflectivity of a desired glass side transmittance color may be combined with a reflective modulus color of a desired thin film side, including a low reflectance modulus color of the thin film side. Including layers 4 and/or 10 in a Low-E coat stack allows the color, reflectance, and solar performance of the coated product to be balanced and tuned.

Coated products made according to embodiments herein are characterized in that the clear glass 1 may be provided with a coating 30 that provides the appearance of a lightly colored block glass—but the glass substrate 1 may be actually transparent or substantially translucent in color itself. By reducing the reflectivity of the side/outside of the glass with a color and/or reflectivity-adjusting absorber layer (4 and/or 10), a thick infrared reflective layer 7 can be created. Normally, a thick IR reflective layer increases the reflectivity of the glass side, but the absorbing layer(s) in the presence of the thick IR reflective layer 7 does not significantly increase the reflectivity of the glass side.

Representative bronze-colored examples (i.e., glass side reflective color) are described above—see Figures 1-5. This part is in addition to what was mentioned above for models related to the bronze colored product. The light bronze coated product may have a visible transmission of 10 over 55%, preferably 20 over 50%, and more preferably 30 over 48%. An IG unit including a light bronze color coated product can have a visible transmittance of no more than 43%. When the desired color of a plated product and/or IG unit is bronze, layers 4 and/or 10 may include or consist primarily of Ni and/or Cr. However, nickel chromium nitride and/or oxynitride may be used for layers 4 and/or 10 as well. Nb, Zr, and/or NbZr may also be used in certain embodiments of the absorbent layer 4 and/or 10. The oxide and/or oxynitride of Nb, Zr, and/or NbZr may also be used . In a lightly bronzed coated product and/or IG unit, in certain representative examples, layer 10 may not be present. In various representative embodiments, layer 10 may be present while layer 4 is absent. In other embodiments, however, both layers 4 and/or 10 may be included in the coating. Layers 4 and/or 10 may be partially or completely oxided and/or nitrided. The thickness of layers 4 and/or 10 in certain embodiments of a light bronze color coated product and/or IG unit can range from 10 to 150 angstroms, preferably from 25 to 75 angstroms, and more preferably from 30 to 70 angstroms.

However, in certain representative embodiments, layers 3 and 5 may have similar or substantially the same thickness. In certain representative embodiments, layers 6 and/or 8 of a bronze-tinted coated article and/or IG unit may comprise oxide, nitride, and/or oxynitride nickel chromium. In some embodiments, layers 6 and 8 may have the same thickness. However, the invention is not limited to this. Examples of layer thicknesses 6 and 8 include 10 to 150 angstroms, preferably 15 to 75 angstroms, and most preferable 20 to 60 angstroms. The infrared reflective layer 7 may include silver and/or gold in certain representative embodiments. The thickness of layer 7 may range from 100 to 170 angstroms, preferably from 110 to 160 angstroms, and most preferably from 115 to 155 angstroms.

Layers 9, 10, and/or 11 are optional on certain models. In certain representative embodiments, only one of layers 9 and 11 may be present, and layer 10 may not be present. Other embodiments may contain all three layers 9, 10, and 11. In different embodiments, layers 9, 10, and /or 11, and layers 3, 4 and/or 5 are not present. When layers 10 and 11 are not included, in certain embodiments, layer 9 may range from 70 to 1200 angstroms, preferably from 100 to 900 angstroms, and most preferably, from 300 to 700 angstroms. When layers 10 and 11 are listed, layers 9 and/or 11 may range from 70 to 1200 angstroms. In certain embodiments of the bronze-tinted coated article and/or IG unit, layers 10 and 11 may not be present in the coating. In representative models layer 12 may be located above the outermost layer. Layer 12 may enhance the mechanical and/or chemical durability of the coated product made according to representative embodiments. Layer 12 may include oxide, nitride, and/or oxynitride aluminum and/or zirconium Layer 12 may be partially and/or fully oxidized or treated with nitride Layer 12 in certain embodiments may range from 10 to 60 angstroms.

As can be seen from the above, by inserting the absorbent layer between dielectric layers 3 and/or 5, the reflectivity of the glass side of the coated product can be reduced. A stack of stimulated layers according to exemplary embodiments of the present invention shows that a 50% reduction in the reflectivity of the glass side is possible, as well as a reduction in redness on the glass side. The side color of the membrane is also improved. Furthermore, visual enforcement is largely unaffected, and an emissivity of 0.03 is considered good. In the simulation, a low-E coating was applied to a largely transparent glass substrate. An a*g value of 1.2 and a b*g value of 2.8 will cause the painted product to appear bronze colored (albeit less reddish) when viewed from the side/outside of the glass. There will be less side/external reflection of the glass, which is what distinguishes it from an architectural and aesthetic point of view.

6mm glass

In Example 14, the bottom SiNx layer is split, and a NiCr-based metal layer is inserted as a color and/or reflectivity-adjusting absorber layer. The main function of the NiCr layer is to reduce the transmittance and reflection coefficient. Placing this layer between two SiNx layers reduces changes in the layer due to heat treatment.

In Example 15, a NiCr-based layer is also sandwiched between two SiNx layers to reduce visible transmission and glass side/outside reflectivity. Thickening the thickness of the NiCr layer (i.e., 3.4 nm instead of 1 nm, or 34 angstroms instead of 10) improves the reflected color Rout from positive a* (red) and slight negative b* (light blue) to negative a* (green) and noticeable negative b* (blue). However, the thickness of the NiCr-based layers surrounding the silver layer should be reduced in this model.

In Example 15, the NiCr-based layer of Example 15 is reduced, and the thickness of the second silicon nitride layer is increased. Although the value of g may be increased, this stack has good visible transmission and glass-side reflectivity values.

Example 17- Transparent color

Another example of a transparent coating is the following stack, with thicknesses of nanometers:

ZrOx 4.5 nm

Si3Nx 46.1 nm

NiCr 2nm

Ag18nm

NiCr 2nm

Si3Nx 5 nm

NbZrNx 3.4 nm

Si3Nx 9.9 nm

glass substrate

NbZrN x has a reflection index of approximately 2.81 at 550 nm, and k of approximately 2.12. The g value (solar factor) of this stack is approximately 3% better than that without an absorbent layer, and this stack allows the same visual transmittance. Thus, selectivity is increased. Tvis ranges between 41.5 and 44.5 for single coated glass panels. The reflectivity of the glass side ranges between 19 and 22%, a*g ranges between -0.5 and 1, and b*g ranges between -4 and -1. The U value for this stack is between 1.1 and 1.2. The optimal g value (solar factor) for this stack is 0.28.

Example No. 18 - Blue color

A blue painted product was produced. The next stack was sprayed onto a 6mm clear type substrate. The blue coated product included layers of approximate thicknesses as shown above:
