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: n (a) aliphatic amine or substituted aliphatic amine containing at least one primary aliphatic amine group where the aliphatic moiety is ethylene or greater with n (b) at least one amino acid, its corresponding lactam or other amide forming derivative. n Optionally, known Lewis Base catalysts for the epoxy/mercaptan reaction, such as tertiary amines, may also be used. |
