Abstract: The instant invention provides a method for making a cast epoxy resin body and the epoxy formulation therefor wherein the formulation includes a two part system. Component A of the system when mixed with Component B in a ratio of 10 to 40 parts of Component B to 100 parts of Component A undergoes a polymerization reaction to form the solid body. Component A consists essentially of from 40 to 70% by weight epoxy novolac polymer, from 30 to 50% by weight vinyl 3-cyclohexene diepoxide and from 0 to 20% by weight 3,4 epoxy cyclohexylmethyl-3,4-epoxy cyclohexane carboxylate. Component B of the system is a paste anhydride consisting essentially of a mixture of a partially hydrolyzed aryl tetracarboxylic acid dianhydride and an alicylic dicarboxylic anhydride.
