China Titanium Dioxide TiO2 Rutile R909

Product Description:
R909 for coating is rutile titanium dioxide pigment manufactured by the sulfate process with excellent control of particle-size and unique coating technology. It is coated 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. R909 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.
Applications:
R909 is rutile titanium dioxide pigment special for coating. It can be used in a wide range of architectural coatings, water soluble coatings, industrial coatings, powder coatings, special paint for ships, coil coatings, anti-corrosive paint, antifouling paint etc.
