FIELD: chemistry.
SUBSTANCE: invention relates to a composition for external anticorrosion protective coating of steel articles. The composition contains an adduct with active hydrogen atoms, which is a product of reaction of a mixture of at least two epoxide oligomers with epoxy value of the mixture of 3.47-4.7 mg·eq/g and an aromatic amine - diaminodiethyl toluene. The adduct includes, homogenised therein, dialkyl phthalate, shale oil and salicylic acid.
EFFECT: invention enables to obtain a composition with low toxicity while maintaining high processing characteristics and protective properties of the cured coating even with high content of plasticiser of up to 45%.
