Titanium Dioxide Rutile R-838 25/1
TITANIUM DIOXIDE RUTILE R-838 25/1 is a non-toxic and chemically stable white powder pigment, produced by the sulfuric acid method. This general-purpose rutile titanium dioxide, treated with inorganic silicon-aluminum coating and special organic solvents, offers excellent dispersibility due to the air-drying process in the final stage of its production. In addition to strong whiteness, brightness, high opacity, and tinting strength, it stands out with superior weather resistance and chalking resistance.
Key Features
R838 is a rutile titanium dioxide pigment surface-treated with inorganic silicon-aluminum and organic solvents. This special structure provides excellent optical brightness, whiteness, tinting strength, weather resistance, and easy dispersibility within formulations.
Applications
This versatile pigment is used in a wide range of applications, including water-based coatings, emulsion paints, powder coatings, and printing inks. It is also widely preferred in high-quality interior coatings, high-solids paints, road marking paints, marine paints, plastics (PVC, polyethylene, polystyrene, polyurethane), rubber, paper, and leather industries.
