POLYFUNCTIONAL POLYCARBONATE POLYOL

摘要

28 Disclosed is a coating composition comprising: (1) a polycarbonate polyol having an average molecular weight of 400-10,000 and a hydroxyl value of 50350, and (2) a melamine resin curing agent, wherein polyhydric alcohols constituting said polycarbonate polyol comprises at least 10 mol % of branched diols, at least 10 mol% of tri- or higher-hydric alcohols and the balance of the other polyhydric alcohols, and a ratio of component (1) / component (2) is within the range of 90/10-50/50 based on solid weight.
