COATINGS COMPRISING AN ORGANOSILANE SOLUTION POLYMER AND A CROSSLINK FUNCTIONAL DISPERSED POLYMER

摘要

A coating composition containing a film-forming organosilane polymer and a sterically dispersed macromolecular polym- er having macromonomer chains which react with the silane functionality of t he organosilane polymer. The coating composition can be used as the clear coat 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.
