COMPOSITION FOR A HEAT-RESISTANT ANTICORROSION COATING

摘要

The invention can be used in various branches of industry and mechanical engineering for protection of surfaces of constructions, for example, steel structures, fuel tanks and vessels used for storage and transportation of all kinds of oil products or various organic solvents, under operating conditions associated with corrosion-active media. The composition contains in percentage by weight: polyurethane pre-polymer based on toluene diisocyanate and diethylene glycol - 55-35%, polytrifluorochloroethylene - 35-55%, aluminum bronze - 5-10%. The dispersity of the aluminum bronze particles not exceeding 20 microns. The technical result consists in provision of thermal resistance of the anticorrosive coating in a range of operating temperatures ±50°C, stable protective properties of the coating when treating the surfaces by steam under pressure of 6 atm at a temperature of 150°C.
