ANTI-CORROSION PROPERTIES OF POLYURETHANE COATINGS WITH FUNCTIONAL FILLERS

The corrosion resistance of steel with modified inhibitory pigments and polyurethane protective coatings was studied by impedance and electrochemical methods. It was found that the combination of a mixture of molybdate / zinc phosphate and calcium silicate in the polyurethane soil due to the synergistic effect enhances its protective properties. Impedance studies have confirmed the increase in anti-corrosion characteristics of such a system.
