Abstract:
A coating composition comprises at least one solvent, at least one resin, and at least one filler, wherein the filler is silica-deficient, sodium-potassium alumina silicate. The silica-deficient filler may be a sodium-potassium alumina silicate that contains less than 0.1 percent by weight crystalline silica and is 5 percent by weight or less of the coating composition or 1 percent by weight or less of the coating composition. In the later instance, the coating composition contains less than 0.001 percent crystalline silica. The resin may comprise styrene, styrenic copolymers, or mixtures including styrene. The composition provides a temporary gloss coating that may be removed physically, as by peeling for example. A method for coating a substrate with a coating that maybe removed by physical means is also provided. The method comprises applying the disclosed coating composition.
