CR537 Rutile Grade Titanium Dioxide Especially for Papermaking
CR537 is a silicon, aluminum inorganic and organic surface treated rutile titanium dioxide, with its average particle size distribution, good water dispersion, good hiding power and high weather resistance properties. It is mainly used in water-based system which demand high water dispersion, such as paper-making, water-based coatings (especially interior and exterior latex paints), and water-based ink production
