(57) [Summary] [Structure] An amine-catalyzed curable coating composition, which comprises a polyol and a polyisocyanate as main components and forms a cured coating film rapidly upon contact with a vapor or atomized amine catalyst, wherein the coating composition is tin or An amine-catalyst-curable coating material, which further contains a bismuth catalyst and a mercaptan compound or polyphenol, and uses a polyol having an acid value of 0 to 8.0 KOHmg / kg as the polyol. And a coating method using the same. [Effect] By using the amine-catalyst-curable coating material of the present invention, rapid curing at a relatively low temperature in amine-catalyst-curable coating is always secured. |
