R900 is produced by sulphate process. It is rutile one for universal use, whose surface is treated with inorganic composite corsisting of aluminum and silica. It has excellent optical character and can be widely used in paint, plastic, ink, paper,etc. R900 has outstanding brightness, hiding power, tinting strength, dispersibility.
