COMPOSITION FOR A HEAT-RESISTANT ANTICORROSION COATING

摘要

The invention can be used in different industrial sectors and machine building for protecting construction surfaces, for example steel fuel tanks and pipelines used for storing and transporting all types of petroleum products or different organic solvents at operation conditions in corrosion-active media. The inventive composition contains 55-35 % by volume toluene diisocyanate and diethylene glycol-based pre-polymer polyurethane, 35-55 % by volume polytrifluorochloroethylene and 5-10 % by volume aluminum powder whose dispersion is equal to or less than 20 mkm. Said invention makes it possible to ensure the heat resistance of the anticorrosion coating within a temperature range of ±50 °C and to provide the coating with protective properties by treating surfaces with water steam at a pressure of 6 atmospheres and a temperature of 150 °C.
