Curing system for curing poliepoxidos, composition of epoxy resin curavel, product substantially insoluvel and infusivel and process for curing poliepoxidos

摘要

More rapid curing of polyepoxide resins is achieved by use of a curing system composed of at least one polymercaptan, at least one catalyst which is a poly[(N,N-dimethylamino)alkyl]ether and/or organic non-quaternized salts thereof derived from organic compounds having at least one acidic group and having a pKa greater than about 3.5 and, optionally, organic sulfide, tertiary phosphine or a tertiary amine having no bridged atoms, having no ether oxygen and having at least one tertiary amine group.
