Abstract:
The present invention provides a hybrid two component coating composition comprising as component I, (A) an N-alkoxysilylalkyl-aspartic acid ester, (B) a polysiloxane having a molecular weight in the range of from about 400 to 10,000, and optionally (C) at least one hydrolyzable silane; and as component II, (D) a polyisocyanate having an average NCO functionality of 2.5 to 5.5 and an isocyanate content, based on solids, of 9 to 50 wt % and containing aliphatic polyisocyanates; and (E) a catalyst. Methods of making and applying the hybrid coating composition are also provided.
