FIELD: chemistry.
SUBSTANCE: present invention relates to an aqueous primer composition. The aqueous primer composition contains: a. at least one composition of a heat-curable self-emulsifying epoxy resin obtained by reacting (a) epoxy resin, (b) a polyatomic phenol and (c) an amine-epoxide adduct, where the amine-epoxide adduct is a product of reaction of an aromatic polyepoxide with polyoxyalkylene amine; b. at least one composition of a heat-curable non-self-emulsifying resin having an epoxide base which has epoxide functionality from 1.8 to 4 and epoxide equivalent weight from 100 to 200; c. water; and d. at least one curing agent. The invention also describes a method of producing the aqueous primer composition.
EFFECT: improved corrosion resistance at low concentrations.
