COMPOSITION FOR COATING INTERIOR OF MOLD

摘要

PURPOSE:To obtain a one-can type epoxy-based composition for coating the interior of mold, having excellent adhesiveness to SMC and BMC. CONSTITUTION:A composition for coating the interior of mold comprises 100 pts.wt. epoxy group-containing epoxy (meth)acrylate having 30-80% reaction ratio of epoxy group obtained by reacting an epoxy resin with (meth)acrylic acid, 20-200 pts.wt. ethylenic monomer containing no carboxyl group and 0.5-30 pts.wt. carboxyl group-containing ethylenic monomer as essential components.
