Features Of Tihai THR218 Titanium Dioxide

  1. High refractive index for exceptional opacity and hiding power in demanding coating systems.

  2. Surface-treated with silica and alumina to enhance dispersion stability and reduce photochemical activity.

  3. Optimized particle size distribution for improved gloss retention and reduced haze in clear topcoats.

  4. Low oil absorption (≤18 g/100g) enabling higher pigment loading and improved formulation efficiency.

  5. Excellent compatibility with both polar and non-polar resin systems, including acrylics, polyesters, and alkyds.

Typical Applications Of Tihai THR218 Titanium Dioxide

  1. Automotive OEM and refinish coatings requiring high color fidelity and durability.

  2. Industrial maintenance coatings for metal protection in aggressive environmental conditions.

  3. High-performance architectural coatings, especially premium exterior elastomeric and low-VOC formulations.

  4. Plastic masterbatches for engineering resins where thermal stability and minimal yellowing are critical.
