Abstract
PURPOSE: To prepare a resin composition having excellent crack resistance and suitable for the casting of electrical devices, at a low cost, by compounding specific bisphenol A type epoxy resin, a curing agent, a reaction catalyst, and a filler.
CONSTITUTION: The objective resin composition is prepared by (1) compounding (A) 90W96pts.wt. of a bisphenol A type epoxy resin of formula wherein the polymerization degree (n) is 0, (B) 4W10pts.wt. of the epoxy resin wherein n is ≥3, (C) 65W95pts.wt. of a curing agent selected from methyltetrahydrophthalic anhydride and methylhexahydrophthalic anhydride or their mixture, and (D) a tertamine, pref. imidazole, etc. as a reaction catalyst, and (2) adding a powdery filter consisting of ≥98% SiO2 to the composition in an amount of 50W80wt%.
