Abstract
A coating system includes a clear coat layer and a sealant. The clear coat layer is formed from a clear coat composition that comprises a crosslinkable carbamate-functional resin and an aminoplast. Optionally, the coating system further includes a sub-clear coat layer. The sealant is bonded to the clear coat layer opposite the sub-clear coat layer. Optionally, the coating system further includes a tie coat layer and that is disposed between the sealant and the clear coat layer. An adhesion promoter is present in the clear coat composition in an amount of less than or equal to about 3% by weight based on the total weight of resin solids of the clear coat composition. Further, the adhesion promoter is present in at least one of the sub-clear coat composition and the tie coat composition in an amount sufficient to increase adhesion between the clear coat layer and the sealant.
