Abstract
PURPOSE:To obtain the title resin composition excellent in cracking resistance and workability and free of loss of heat resistance, by mixing an epoxy resin with a specified polycarboxylic acid anhydride and a filler. CONSTITUTION:A resin composition comprises an epoxy resin, a polycarboxylic acid anhydride of the formula (wherein m and n are each 2-20) and 5-50pts.wt. filler per 100pts.wt. liquid acid anhydride. As the epoxy resin, one which is liquid at room temperature is desirable. As a cure accelerator, benzyldimethylamine, 2-ethyl-4-methylimidazole or the like which can give a mixture of good stability and has good solubility in an epoxy resin is used. It is desirable that part of the filler used is talc mainly comprising hydrated magnesium silicate which is a flaky powder. As the talc, one free of impurities such as Al2O3, Fe2O3 and CaO is desirable.
