High Gloss Titanium Dioxide Rutile TiO2 XR-290 from China Suppliers - Ideal for Inks and Coatings Factory
Rutile Titanium Dioxide (TiO₂) XR-290 is a rutile-grade white pigment powder designed to provide strong optical performance and reliable processing behavior. With a high refractive index, rutile TiO₂ typically offers excellent opacity (hiding power) and high tinting strength, helping finished products achieve improved whiteness, brightness, and gloss, along with a cleaner base color and stable undertone.
XR-290 is commonly engineered with surface treatments to enhance overall formulation performance. These treatments often include inorganic coatings (such as silica and/or alumina) combined with organic surface treatment, which can improve wetting and dispersion, reduce oil absorption, and minimize agglomeration and settling. Better dispersion and rheology stability can translate into smoother appearance, improved consistency, and easier processing in both coatings and plastics.
Rutile grades are also valued for strong weather resistance, heat resistance, and chemical resistance, supporting durability in demanding applications and helping reduce risks of chalking, fading, yellowing, or discoloration during outdoor exposure or harsh service conditions.

For best results, pre-wet the pigment with the binder/solvent system, select a compatible dispersant, and apply high-speed dispersion or milling to reach target fineness and maximize opacity and color consistency. Store in a cool, dry place with tight sealing, protect from moisture, heat, and direct sunlight, and follow MSDS guidance for safe handling.
