AUTOMOTIVE COATING COMPRISING AN ORGANOSILANE POLYMER

摘要

2099618 9211328 PCTABS00014 A coating composition containing a film-forming organosilane polymer and a sterically dispersed macromolecular polymer having hydroxy or silane functional macromonomer chains which react with the silane functionality of the organosilane polymer. 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.
