Sulfate Grade R838-Coatings/Paints
TTiO2 R-838 rutile is a generic titanium dioxide prepared by the sulfuric acid method that is a non-toxic, chemically stable white powder treated with a silicon-aluminum coating and special organic solvents. After air-drying late in the production process, R-838 has excellent dispersibility and a strong whiteness, brightness, glossiness, and good hiding power, achromatic power, as well as excellent weather-resistance and non-chalkiness.
Recommended applications:
| ◾️ Water-based Coatings | ◾️ Emulsion Paint |
| ◾️ Powder Coatings | ◾️ Printing Ink |
| ◾️ Other Areas |
Key features:
| ◾️ It Has An Excellent Optical Brightness |
◾️ Glossiness |
| ◾️ Whiteness | ◾️ Tint-reducing Power |
