ABSTRACT:
A coating composition containing a film-forming organosilane polymer and a sterically dispersed polymer having macromonomer chains which react with the silane functionality of the organosilane polymer. Silane functionalities in the core of the dispersed polymer provides post-cure crosslinking in the core. The coating composition can be used as the clearcoat over a conventional pigmented basecoat, or as a basecoat or monocoat or primer when a suitable amount of pigment is incorporated therein. The coating composition provides improved chemical resistance and is not prone to cracking.
