Titanium Dioxide R-2902

vellischem — Wed, 26 Jun 2024 05:59:32 +0000

Rutile TiO₂ 2902 is a silicon / aluminum treated rutile titanium dioxide white pigment produced by the chloride process. It is designed to be a universal multipurpose grade of TiO₂ combining excellent optical properties with good durability for both interior and exterior applications. It has high gloss, good opacifying power with high tint strength and good exterior weathering properties.

Rutile TiO₂ 2902 is recommended for all types of coatings: Architectural, industrial, maintenance coatings; solvent based or waterborne; interior or exterior.

Rutile TiO₂ 2902 is also recommended for use in building materials as well as in plastics (PVC, PE etc), for low abrasivity pigments for letterpress, gravure, polyamide and other inks, for ceramics, for the paper industry, and other applications.

GreenChrome GX

Green Chrome Oxide GX is a high quality pigment grade chrome oxide green. Compared to other green pigments, chromic oxide is weather stable, gives excellent light fastness, durability, stability and performance. It is also unaffected by acids, alkalis and solvents. The product is used extensively in the coloration of construction materials. In addition, the pigment can also be used for the coloration of glazes, enamels or engobes in the ceramic industry. It is easy to break down and distribute to reach its final tinting strength quickly.
