FIELD: chemistry.
SUBSTANCE: invention relates to a curing agent, suitable for curing of epoxy resins, epoxy resin composition and use thereof, to a cured composition, as well as to an article. Curing agent contains an amine of a formula described below and at least one polyamine, containing at least three amine hydrogens, capable of reacting with epoxy groups. Epoxy resin composition contains at least one epoxy resin and said curing agent. Cured composition is obtained by curing epoxy composition to produce a coating. Article is obtained by applying epoxy composition on a substrate surface.
EFFECT: invention enables to obtain a curing agent with weak smell, low viscosity, which shows no tendency to drying or precipitation in air and can harden without turbidity under conditions of moisture content and low temperatures, as well as obtain even non-adhesive film with high hardness.
