Rutile Titanium Dioxide R818

Rutile titanium dioxide R818 is a generic titanium dioxide prepared through the sulfuric acid method and is a non-toxic, chemically stable white powder treated with a zirconium-aluminum coating by a special organic process. It has good whiteness, brightness, glossiness, and hiding power, and is achromatic, with good dispersibility and excellent weather-resistance and non-chalkiness.

 

1. Characteristics:

Titanium dioxide R818 series  is a general-purpose multi-purpose titanium dioxide pigment. The surface is treated with dense zirconium, aluminum inorganic coating and special organic treatment. 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, excellent hiding power and achromatic power, good dispersibility and stability.
