摘要
The presence of an acid catalyst in a clearcoat composition enables the production of a wrinkle-free coating in a process comprising the simultaneous curing of applied layers of both a waterborne basecoat composition as well as a solventborne clearcoat composition. The waterborne basecoat composition comprises an organic resin, a crosslinker, and a free amine. The solventborne clearcoat composition comprises an acid catalyst in an amount significantly higher than the quantity normally used in high solids original equipment manufacturer clearcoat compositions, a polymer which is crosslinkable with melamine, and a monomeric melamine type crosslinking resin for crosslinking the polymer. The process is most preferably used to make an automotive quality topcoat.
