Abstract: A multicoat coating system that does not contain a primer layer over an electrodeposition coating layer. Even in the absence of the primer layer, the electrodeposition coating layer is protected from ultraviolet light by a basecoat layer that contains a UV blocking composition comprising at least two of carbon black, iron oxide, titanium dioxide, and an aluminum pigment or mixtures of any these.

Abstract: The invention provides a clearcoat coating composition containing either one acrylic polymer with secondary hydroxyl functionality and carbamate functionality or two acrylic polymers, the first having secondary hydroxyl functionality and the second having carbamate functionality; a carbamate-functional or urea-functional material that is the reaction product of (1) a compound comprising a primary carbamate or primary urea group and an hydroxyl group and (2) a compound that is reactive with hydroxyl groups on a plurality of molecules of compound (1), but that is not reactive with the carbamate or urea groups on compound (1); and a crosslinking component including an aminoplast crosslinker. A windshield sealant can be applied directly to the clearcoat layer produced from the composition without the need for a special primer layer.
