FIELD: anti-corrosion coatings.
SUBSTANCE: invention can be used for applying anti-corrosion coatings. The aqueous composition of the coating agent contains particles of an isocyanate-reactive polymer with an average particle size of 10 to 1000 nm, a polyisocyanate blocked by ketoxime and/or pyrazole containing an aromatic or cycloaliphatic hydrocarbon residue, a polyanionic polymer, a complex fluoride and an aminosilane. Complex fluoride is a hexa- or tetrafluoride of metals IVb, Vb and VIb of groups of the periodic system of elements. The aqueous composition of the coating agent has a pH value of 3 to 5 and a total solids content of 5 to 35% by weight. Also proposed are a method for manufacturing an aqueous composition of a coating agent, a method for coating a surface of a substrate releasing metal ions, and a coating.
EFFECT: providing easy-to-apply aqueous solution coating compositions without the use of electric current, which are corrosion resistant and uniform.
