Abstract
A method for producing coated, molded, fiber-reinforced thermoset plastic articles having an adherent coating in heated matched metal molds. The coating composition includes a polyurethane polyacrylate which is a reaction product, substantially free of unreacted --NCO radicals, of an organic diisocyanate, a hydroxy alkyl acrylate or methacrylate and an organic diol in combination with copolymerizable alpha-, beta-ethylenically unsaturated monomer. The coating composition also contains initiators for addition polymerization and may contain fillers including inert paticulate fillers, pigments, mold release agents. The coating composition is applied in the matched metal mold after a fiber-reinforced thermoset plastic article has been shaped within the mold. The coating composition is applied by opening the mold and introducing the described coating composition, thereafter closing the mold and retaining the mold in the closed condition until the plastic article is further cured and the described coating composition is cured.
