A protected substrate, comprising:
- a planar substrate comprising a surface;
- and
- a burn-off temporary protective layer positioned over at least a portion of the surface,
- wherein the burn-off temporary protective layer comprises a wax, a polyolefin, a polyester, a polycarbonate, a polyether, or some combination thereof,
- wherein the burn-off temporary protective layer is removable by a heat treatment process that does not substantially damage the surface.
A method for protecting a substrate, comprising:
- providing a planar substrate comprising a surface;
- and
- applying a material to form a burn-off temporary protective layer over at least a first portion of the surface,
- wherein the burn-off temporary protective layer comprises a wax, a polyolefin, a polyester, a polycarbonate, a polyether, or some combination thereof,
- wherein the burn-off temporary protective layer is removable by a heat treatment process that does not substantially damage the surface.
A method of removing a burn-off temporary protective layer from a coated substrate, comprising:
- providing a coated substrate comprising a surface over a portion of which a burn-off temporary protective layer is applied, wherein the burn-off temporary protective layer comprises a wax, a polyolefin, a polyester, a polycarbonate, a polyether, or some combination thereof;
- and
- removing the burn-off temporary protective layer from the surface by burning the burn-off temporary protective layer to form an unprotected substrate without substantially damaging the surface.
