ABSTRACT:
The invention relates to a color pigmented moisture-curing polyurethane coating that cures to form a film having a matte finish, as well as methods of producing the coating. The coating is suitable for use as a protective and/or decorative coating. The coating comprises one or more specified color pigments, polyisocyanates, polyols, tertiary amines, and a matting agent or agents. The combination of constituents provide a finished form coating with highly controlled gloss and sheen characteristics. Additional optional ingredients may be added to the coating composition, including catalysts, ultraviolet light stabilizers, wetting agents, solvents, and agents to increase slip and flow.
