Abstract
Official abstract text for this publication.
The epoxy resin molding material of the invention comprises (A) an epoxy resin and (B) a curing agent, wherein the (B) curing agent contains a polyvalent carboxylic acid condensate. The thermosetting resin composition of the invention comprises (A) an epoxy resin and (B) a curing agent, wherein the viscosity of the (B) curing agent is 1.0-1000 mPa·s at 150° C., as measured with an ICI cone-plate Brookfield viscometer.
First claim
