HR-258
HR-258 series rutile titanium dioxide is a general-purpose product and one of the main products. The imported sand mill is used for wet grinding, and the particle size distribution is good; the surface treatment of dense inorganic coating is carried out with silicon oxide and aluminum oxide, which has excellent pigment performance.
Detailed introduction
HR-258 series rutile titanium dioxide is a general-purpose multi-purpose titanium dioxide pigment. The surface is treated with dense zirconium, aluminum inorganic coating and special organic treatment. The product design goal is close to the quality standard of similar products in foreign countries. It has high whiteness, high gloss, bluish background, fine particle size and narrow distribution, high ultraviolet absorption ability, excellent outdoor weather resistance, strong anti-powdering ability, super hiding power and achromatic power, and good dispersibility. , good stability and other characteristics, the products made of it have bright colors and high glossiness.
