    摘要: An epoxy resin composition comprising an epoxy resin, a curing agent, and an inorganic filler has a melt viscosity of at most 150 poise at 175.degree. C. The inorganic filler has a BET specific surface area of 1.5-6 m.sup.2 /g and is such that when a 75/25 mixture of the inorganic filler and a bisphenol F type liquid epoxy resin is measured for viscosity at shear rates of 0.6/sec. and 10/sec. at a temperature of 25.+-.0.05.degree. C. by an E type viscometer, the ratio of the viscosity at 0.6/sec. to the viscosity at 10/sec. is at least 3.5/1. The amount of the inorganic filler loaded is 80-90% by weight of the composition. The composition is suitable for the encapsulation of matrix frames.
