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.
