Abstract
A thermosetting solvent solution coating composition is disclosed which cures to provide the appearance of anodized aluminum. This composition comprises a dispersion of a fluorocarbon polymer in volatile organic solvent which is pigmented with a finely divided mica (preferably titanium dioxide coated) and an aluminum flake (which is preferably acid-resistant) to provide a combination of whiteness and transparancy providing an anodized aluminum appearance. This pigmented dispersion contains a thermosetting acrylic, preferably an hydroxy-functional acrylic copolymer and a curing agent therefor to provide a thermosetting cure which enhances the hardness and abrasion resistance of the coating, and enough additional pigment to provide sufficient coloration to allow production control without providing enough opacity to hide the whiteness and metallic appearance provided by the combination of mica and aluminum flake. A flatting agent to reduce gloss and a wax to enhance surface lubricity are also preferably present.
