FORTIFIED EPOXY RESIN COMPOSITIONS AND PROCESS FOR THE PREPARATION THEREOF

摘要

Heat curable epoxy resin compositions comprising a resin-forming polyepoxide and an amine curing agent are fortified (i. e. given increased strength and modulus but without consequent brittleness) by incorporating into the resin mix prior to curing up to 40 parts by weight per hundred parts of resin of a fortifying agent which is the reaction product of an aromatic amine, e. g. aniline, with a mono- or di-epoxide, the fortifier thus obtained optionally further being reacted with an isocyanate or nitrile prior to incorporation into the resin mix.
