Patent ID: 8114481

Claim:
A process for producing a coating on a substrate, said process comprising the steps of: (A) mixing components of a coating composition to form a pot mix, wherein said coating composition consists of: i) 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 35 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; and ii) a crosslinking component consisting of a polyisocyanate compound having two or more isocyanate groups that react with the crosslinkable groups at temperatures in a range of from 40° F. (4° C.) to 200° F. (93° C.); iii) one or more pigments or effect pigments; and iv) 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; (B) applying the pot mix over the substrate to form a layer; and (C) curing the layer on the substrate to form said coating.
