EPOXY RESIN MOLDING MATERIAL FOR SEALING

摘要

PURPOSE:To provide a molding material containing a reaction product of an epoxy resin and a polybutadiene polymer, having improved crack resistance and excellent moldability and free of mold staining and stick in the mold. CONSTITUTION:The objective material contains a reaction product of an epoxy resin and a polybutadiene polymer. A polyfunctional novolak epoxy resin is used as the epoxy resin and 100pts.wt. of the resin is compounded with 0.5-50 pts.wt. of a polybutadiene polymer.
