Process with excellent control of particle-size and unique coating technology. It is coate r915 for coating is rutile titanium dioxide pigments manufactured by the sulphate d with inorganic and special organic surface treatment. It has excellent pigment properties, with good whiteness and gloss, excellent hiding power strong tinting strength, superior weatherability and chalk resistance, is easy wetting and easy to disperse. R915 can endow the coating film bright color, enhance its mechanical strength & adhesion and keep it from crazing. It can also prevent the penetration of uv or moisture, improving the chalk resistance of film to extend its working life.
