Powder composition of epoxy resin, high melting acid anhydride and calcium silicate

摘要

A thermosetting epoxy resin based powder composition composed of an epoxy resin, a high-melting point polycarboxylic acid anhydride and calcium silicate as a filler, the high-melting point polycarboxylic acid anhydride comprising fine particles of 5 to 149 mu m in average size that have reacted with the epoxy resin in the molten state on their surfaces.
