FIELD: chemistry.
SUBSTANCE: invention relates to the preparation of amine curing agents for epoxy paint compositions for the creation of coatings with high physical-mechanical and anticorrosive properties, curing under adverse conditions. Amine curing agent for epoxy paint and varnish compositions, which is a the reaction product of 4,4'-diphenylolpropane, formaldehyde and aliphatic amines (diethylenetriamine or triethylenetetramine) at a temperature of 80±0.5 °C and a molar ratio of components of 1:4.5:(3.2–4.1), respectively.
EFFECT: proposed hardener allows to reduce the drying time of epoxy compositions at low temperatures and high humidity.
