EPOXY MATRIX RESIN FORMULATIONS WITH IMPROVED STORAGE STABILITY

摘要

Epoxy resin formulations having improved storage stability comprising epoxys selected from the group consisting of polyglycidyl ethers of polycyclic bridged hydroxysubstituted polyaromatic compounds and N,N,N',N'-tetraglycidyl-bis(4-amino-3-ethylphenyl) methane with from about 6 to about 150 pbw, per hundred parts by weight of the epoxy resin components, of a solid aromatic diamine hardener insoluble in said composition at room temperature in an amount effective to cure said epoxy resin.
