FIELD: corrosion protection.
SUBSTANCE: invention is designed for use in oil and gas industry, mechanical engineering, in particular to protect internal surfaces of steel fuel tanks and mains, wherein all kinds of petroleum products or various organic solvents can be present. Composition contains 55-35 vol % pre-polymerized polyurethane based on tolylenediisocyanate and diethylene glycol, 35-55 vol % polytrifluorochloroethylene, and 5-10 vol % aluminum powder with particle size no larger than 20 μm.
EFFECT: achieved heat resistance of anticorrosive coating within a working temperature range ±50°C and protective properties of coating when surfaces are treated with steam at 150°C and pressure up to 6 atm.
