Patent ID: 7666477

Claim:
A process for coating substrates assembled from metal parts and at least one polymeric part, with visible metal and plastic surfaces, comprising the successive steps of (1) electrodeposition coating the substrates, removing non-deposited electrodeposition coating agent from the substrate and thermally cross-linking the deposited electrodeposition coating by baking at an oven temperature of up to about 200 to about 220° C., and thereby forming an electrodeposition coating primer on the metal surfaces, and (2) applying and curing at least one coating on the visible surfaces of the substrate, wherein at least some of the polymeric parts making up the visible surfaces of the substrate comprise a polyamide composition comprising: a. about 40 to about 98 weight percent polyamide; b. about 1 to about 20 weight percent novolac resin; c. about 1 to about 30 weight percent toughener; and d. 0 to about 40 weight percent mineral filler, where the weight percentages are based on the total weight of the composition.
