TH-901 anticorrosive coating is a single component of normal temperature curing coating composed of chemically modified raw paint as resin substrate and key pigment components by various forms.


Performance: TH-901 coating has outstanding heat resistance and oil resistance besides acid, alkali, water, seawater and corrosion resistance. Therefore, it breaks through the limitation of durable corrosion resistance of heat exchanger in oil refining industry under inferior conditions of high temperature (150-300 C)+oil (crude oil, gasoline, diesel oil, etc.), and is widely used in oil extraction, refining and oil storage.
