Heat-resistant and corrosion-resistant coating for heat exchangers

Thread Content

The heat-resistant and anti-corrosive coating for heat exchangers that cures at room temperature is a special functional coating designed specifically for use in heat exchanger applications. The main types of such products and their performance characteristics vary depending on the required heat resistance levels and operating conditions; common products include TH-901, a specialized anti-corrosion coating for cooling equipment. Key parameters of TH-901: it is a one-component coating that can cure at room temperature or with heating, with long-term heat resistance ranging from 150°C to 240°C, and a maximum design heat resistance of 300°C. Advantages: Using modified raw lacquer as the base material, it overcomes the limitations associated with using hot oil as a medium for corrosion protection; it possesses resistance to oils, acids, alkalis, and seawater, as well as to steam cleaning. The coating has a low thermal resistance after curing, which helps improve heat exchange efficiency. It thus solves the problem of corrosion protection in heat exchangers used in the oil refining and extraction industries. Applicable scenarios: Carbon steel heat exchangers, oil-water heat exchange equipment, reboiler tubes, etc. in the petrochemical industry operating at temperatures of 150°C–300°C.
