Fortifier or strengthener for anhydridecured epoxy resins and anhydride curable epoxy resins containing it.

摘要

An anhydride-cured epoxy resin (epoxy resin plus anhydride curing agent plus catalyst) may be fortified (i.e. increased in strength and modulus without being made brittle) by the addition of a fortifying agent comprising a mixture of a carboxylic acid and the reaction product of a carboxylic acid anhydride and a substituted aromatic amine.
