发明名称 Low VOC, heat-curable, one-component and two-component coating compositions based on organic polyisocyanates
摘要 The present invention relates to a process for coating a substrate which comprises (a) contacting said substrate with a low volatility organic (so-called "low VOC") coating composition having a viscosity as measured by ZAHN cup 2 of less than about 200 seconds and consisting essentially of at least one polyisocyanate, a solvent in an amount of between 0% and 45% by weight based upon the amount of said polyisocyanate in said composition, and an trimerization catalyst, said composition being essentially free of any volatile mono- and di-isocyanates, to form a coating on said substrate, and (b) heating said coating to a curing temperature of between 120 DEG F. and 350 DEG F. for a curing time of between about ten minutes and about six hours in order to cure said coating by trimerizing at least some of the isocyanate groups of the polyisocyanate to provide a heat-cured coating on said substrate. Also claimed is the coating composition itself.
