Color plus clear coating method utilizing addition interpolymers containing alkoxy silane and/or acyloxy silane groups

摘要

Disclosed is a method for coating a substrate comprising the steps of (a) forming a basecoat by coating the substrate with a pigmented basecoating composition; and (b) thereafter forming a topcoat by coating the basecoat with a clear topcoating composition; wherein at least one of the basecoating composition and topcoating composition contains an addition interpolymer having alkoxysilane and/or acyloxysilane moieties, a peak molecular weight of from about 2,000 to about 20,000, and a calculated glass transition temperature of at least about 25 DEG Celsius.
