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. |
