Description
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.
Characteristics
R818 is a titanium dioxide pigment treated with an inorganic silicon-aluminum coating and organic solvents, which has a strong glossiness, and good hiding power, weather resistance, and dispersibility.
Applications
PVC piping, paper making, coatings, plastics, rubber, and master batches
Packaging
25 kg paper-plastic bag; large 500 kg or 1,000 kg bags
