METHOD FOR MANUFACTURING THERMOSETTING RESIN COMPOSITION FOR CASTING, THERMOSETTING RESIN COMPOSITION FOR CASTING AND ELECTORICAL/ELECTRONIC COMPONENT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a thermosetting resin composition for casting superior in impregnating ability, electrical properties and mechanical properties of a hardened product, even when a large amounts of inorganic fillers are added, that controls deterioration in impregnating ability due to inclusion of crushed fine powders and controls inclusion of a metallic component due to abrasion of a mixing vessel.;SOLUTION: This resin composition comprises (A) a 100 pts.wt. epoxy resin and (B) a 150-300 pts.wt. inorganic filler as essential components. The method for manufacturing the resin comprises addition of (B) the inorganic filler, after heating (A) the epoxy resin to a temperature of ≥100°C to ≤200°C.;COPYRIGHT: (C)2006,JPO&NCIPI
