Abstract:
1. A coating composition curable at ambient temperatures, said coating composition consisting of: (A) a crosslinkable component consisting of 15 to 99 weight percent of total solid weight of the crosslinkable component a polyester having hydroxyl crosslinkable groups and a weight average molecular weight in a range of from 1500 to 100,000, and 1 to 15 weight percent of total solid weight of the crosslinkable component a melamine having crosslinkable groups selected from an —NH group, a hydroxyl group, or a combination thereof; (B) a crosslinking component consisting of a polyisocyanate compound having two or more isocyanate groups that react with the crosslinkable groups at ambient temperatures in a range of from 40° F. (4° C.) to 200° F. (93° C.); (C) one or more pigments or effect pigments; and (D) one or more additives selected from conductive additives, viscosity adjuster, catalyst, one or more solvents, or a combination thereof; wherein said coating composition is formulated as a primer, or a color matched primer.
