Abstract

PURPOSE:To obtain the title compsn. having low viscosity and high heat resistance and being useful for heat-resistant electric insulation coil, comprizing a specific multi-functional epoxy resin, a bifunctional epoxy resin, an acid anhydride curing agent and a curing catalyst. CONSTITUTION:A thermosetting resin compsn. can be obtd. by compounding 1pt.wt. multi-functional epoxy resin represented by the formula (wherein R is alkylene or aralkylene) contg. 3 or more p-(2,3-epoxypropoxy)phenyl groups (A), 0.1-19pts.wt. bifunctional epoxy resin (e.g., bisphenol A diglycidyl ether) (B), an acid anhydride curing agent (e.g., methylhexahydrophthalic anhydride) (C) and 0.001-10wt.% curing catalyst (e.g., trimethylamine). A conductive material wound with an insulating base material is impregnated with this compsn. and a heat-resistant electric insulation coil is obtd. by heating and curing it.
