Abstract
The process for molding a thermoset sheet-molding composition or bulk-molding composition is provided that includes the exposure of a mold surface to a silsesquioxane monomer or pre-polymer material under conditions to induce polymerization of said material or said monomer to form a mold release coating on the surface. The thermoset sheet-molding composition or bulk-molding composition is then injected into the mold and into contact with said coating under conditions to cure the composition to form an article.
