FIELD: chemistry.
SUBSTANCE: method involves preparing a steel surface, applying a polymer layer by immersing the surface into a bath with an aqueous solution of an oligomer, and curing the applied polymer layer. Preparing the surface involves removing oxidised films and de-fatting. The polymer protective coating is cured at room temperature; the oligomer is N-octofluorpentyl-substituted oligocaproamide.
EFFECT: invention enables producing the protective coating exhibiting hydrophobic and anti-corrosion properties of the steel surface.
