ABSTRACT:
A coating composition for use in a mold coat coating process wherein the coating composition is previously coated on the molding surface of a mold for polyurethane resin, prior to molding of the polyurethane resin in which the coating composition is transferred onto the surface of the molded polyurethane resin. The coating composition is comprised of a principal component including a resin constituent whose principal ingredient is addition polymer of isophorone diisocyanate and polycarbonate polyol in a content ranging from 8 to 25% by weight of the principal component, and a hardener component including a resin constituent whose principal ingredient is addition polymer of hexamethylene diisocyanate and isophorone diisocyanate in a content ranging from 5 to 100% by weight of the hardener component, thereby improving pot life and weatherability of coating film of the coating composition while contributing shortening of so-called open time in a molding cycle.
