摘要
Extremely rapid ambient curing of polyepoxide resins and mixtures of polyepoxide resins and polyacrylate esters is achieved by use of a curing system composed of at least one polymercaptan and at least one catalytic co-curing agent which is the condensation product of: (a) aliphatic amine or substituted aliphatic amine containing at least one primary aliphatic amine group where the aliphatic moiety is ethylene or greater with (b) at least one amino acid, its corresponding lactam or other amide forming derivative. Optionally, known Lewis Base catalysts for the epoxy/mercaptan reaction, such as tertiary amines, may also be used.
