FIELD: chemical or physical processes.
SUBSTANCE: invention relates to production of epoxy resin hardeners. Disclosed is a method of producing a hardener by chemical reaction of aromatic amine—tri-(p-aminophenyl)methane with cycloaliphatic dioxide—3,4-dioxycyclohexylmethyl-3',4'-epoxycyclohexanecarboxylate—by mixing in a reactor with a high-speed mixer in the presence of a catalyst—furfuryl alcohol.
EFFECT: obtained hardener enables to cure cycloaliphatic epoxy resins to obtain resins with high physical and mechanical properties.
