PS material is an innovative cross-linked reaction material formed by polymer & modified silicate. PS material combines advantages of chemical resistance from inorganic silicate and mechanical properties from organic isocyanate. Therefore, a dense protective coating layer is formed, inducing long-term corrosion resistance against strong acids, strong alkaline, high salinity, oils, organic solvents, and most other chemicals. PS material is environmentally-friendly, non-toxic, flame retardant, primerless, and construction easily. Application quickly by brushing, rolling, scratching & spraying it on the surface of carbon steel, stainless steel, alloys, concrete, and etc. PS material is widely applied to marine engineering, energy industry, large-scale industrial enterprises, modern transportation & logistic, and municipal utilities.
