FIELD: chemistry.
SUBSTANCE: invention relates to amine curing agents for epoxy resins. Disclosed is a curing agent for epoxy resins, containing an amine with at least one amino group of formula (I) and an amine with at least one amino group of formula (II), where X is 2-hydroxyphenyl and ratio between number of amino groups of formulae (I) and (II) ranges from 0.05 to 1.0. Technical result is disclosed curing agents have weak smell and low viscosity, harden fast with epoxy resins, without yielding turbidity during production of films with high strength and resistance.
EFFECT: disclosed formulations of epoxy resins are particularly suitable for coatings with low level of emission.
