<p>PURPOSE:The titled composition excellent in heat cycling resistance, heat resistance and moisture resistance, comprising a polyfunctional epoxy compound, a phenol novolak resin, an inorganic filler, a cure accelerator and a fluorocarbon resin. CONSTITUTION:A polyfunctional epoxy compound (A) (e.g., novolak epoxy resin) is mixed with a phenol novolak resin (B) of an unreacted monomer content <=0.5wt%, 50-80wt% inorganic filler (C) (e.g., crystalline silica powder), a cure accelerator (D) (e.g., 2-methylimidazole) and a fluoroelastomer (D) (e.g., trifluorochloroethylene/vinylidene fluoride copolymer) of a particle diameter <=50mum so that the ratio of E (pts.wt.) to (A+B+E) (pts.wt.) may be 0.02-0.3.</p> |
