    CPC classification number: C08G59/184

    Abstract: Process for the manufacture of new adducts of polyepoxides and polyamines suitable for use as curing agents for epoxy resins characterized in that (1) a 1,2-polyepoxide compound is reacted with (2) a cycloaliphatic-aliphatic diprimary diamine in which the first primary amino group is located on an aliphatic sidechain and the second primary amino group is bonded to an endocyclic carbon atom of the cycloaliphatic ring, in a quantity ratio of 0.6 to 1.2 mols, preferably 0.7 to 1.0 mols, of the diamine (2) per 1 epoxide equivalent of the polyepoxide compound (1), with heating.

    CPC classification number: C08G59/184

    Abstract: NEW ADDUCT AGENTS FROM A POLYPHENOL-POLYGLYCIDYL ETHER (SPECIAL LIQUID DIOMETHANE-DIGLYCIDYL ETHERS, SUCH AS EPI Z) AND A CYCLOALIPHATIC DI-PRIMARY DIAMINIE ("ISOPHORONEDIAMINE", 4,4''-METHYLENE-BIS-(2METHYL-CYCLOHEXYLAMINE)) WITH AN EXCESS OF 1.5 TO 2.7 MOLS OF DIAMINE BEING USED PER 1 EPOXIDE EQUIVALENT OF THE POLYGLYCIDYL ETHER. BY ADDITION OF DILUENTS OF LOW VOLATILITY (DIBUTYL PHTHALATE, POLYPROPYLENE GLYCOL OR TRIMETHYLHEXAMETHYLENEDIAMINE) LIQUID CURING AGENT FORMULATIONS ARE OBTAINED FOR "SOLVENT-FREE" LACQUERS BASED ON LIQUID EPOXIDE RESINS. AS A RULE PHENOLS (DIOMETHANE, "TRIS-MANNICH") ARE FURTHER ADDED AS ACCELERATORS TO THE CURING AGENT FORMULATIONS. THE LACQUERS FORMULATED WITH THE NEW ADDUCT CURING AGENTS, IN CONTRAST TO KNOWN LACQUERS BASED ON CYCLOALIPHATIC DIAMINES AS SUCH, DO NOT TEND TO SURFACE FAULTS OF THE FILMS WHEN CURED AT ROOM TEMPERATURE.
