Abstract

PURPOSE: To provide an epoxy resin compsn. which produces a cured article having excellent heat resistance, thermal shock resistance and tracking resistance, containing a hydrogenated bisphenol A type epoxy resin a bisphenol A type epoxy resin, an acid anhydride and a hydrated alumina.
CONSTITUTION: There is provided a resin compsn. contg. an epoxy resin (consisting of a mixt. of a hydrogenated bisphenol A type epoxy resin having an epoxy equivalent of 180W230 and a bisphenol A type epoxy resin havig an epoxy equivalent of 180W1,000 in a weight ratio of 30/70W70/30), an acid anhydride which is liquid at ordinary temperatures, and fillers of which 5W50wt% is hydrated alumina having an everage particle size of 0.5W60μm. When the amount of the hydrogenated bisphenol A type epoxy resin is less than 30pts.wt., tracking resistance and workability are lowered. When the amount is more than 70pts.wt., heat resistance and thermal shock resistance are lowered. Further, when the amount of the bisphenol A type epoxy resin is less than 30pts.wt., heat resistance and thermal shock resistance are lowered. When the amount is more than 70pts.wt., tracking resistance and workability are lowered. Thus, the use of such amounts is not preferred.
