Abstract:
The present invention relates to the polyamines N,N′-diaminopropyl-2-methyl-cyclohexane-1,3-diamine and N,N′-diaminopropyl-4-methyl-cyclohexane-1,3-diamine and mixtures thereof, to the use thereof as curing agents for epoxy resin and to a curable composition comprising epoxy resin and these polyamines. Even at low temperatures this curing agent/the corresponding curable composition cures rapidly and is early-stage water resistant and is thus especially suitable for floor coatings. The invention further relates to the curing of this composition and the cured epoxy resin obtained by curing of this composition.
