NOVEL CATALYSTS WITH STABILISING EFFECT FOR EPOXY COMPOSITIONS Russian patent published in 2015 - IPC C08L63/02 C08G59/42 C08G59/68

Abstract RU 2559492 C1

FIELD: chemistry.

SUBSTANCE: hot-curing epoxy composition includes epoxy-diane oligomer of grade ED-20, curing agent - iso-methyltetrahydriphthalic anhydride (iso-MTHPA) and catalyst of polymerisation reaction. As catalyst it contains aminomethylterpenephenol compounds. Composition contains components with their following content (wt.p.): epoxy oligomer - 100, iso-MTHPA - 80, catalyst - 1-2. As aminomethylterpenephenol compounds used is 4-dimethylaminomethyl-2,6-diisobornylphenol or 6-dimethylaminomethyl-4-methyl-2-isobornylphenol.

EFFECT: increased thermal resistance and mechanical strength of products from said composition.
