EPOXY RESIN COMPOSITION

摘要

Disclosed is an epoxy resin composition containing a siloxane structure, which has excellent corrosive gas resistance. Specifically disclosed is an epoxy resin composition comprising an organopolysiloxane (A) and a polycarboxylic acid (B), wherein the organopolysiloxane (A) is an epoxy resin having at least a glycidyl group and/or an epoxycyclohexyl group in the molecule and the polycarboxylic acid (B) is a polycarboxylic acid having at least two carboxyl groups and also having an aliphatic hydrocarbon group as the main skeleton.
