Protected substrate and method for protecting a substrate

A protected substrate includes a planar substrate having a surface and a burn- off temporary protective layer positioned over at least a portion of the surface. The burn-off temporary protective layer includes a polyurethane layer, an epoxide layer, or a combination thereof. The burn-off temporary protective layer is removable by a heat treatment process that does not substantially damage the surface. Various other protected substrates and methods for protecting a substrate are also disclosed.
