Features Of Xianghai R6658 Titanium Dioxide

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

  2. Surface-treated with silica and alumina to ensure excellent dispersibility and long-term stability in aqueous and solvent-based formulations.

  3. Low oil absorption (< 18 g/100g) enabling high loading efficiency and improved rheology control.

  4. Consistent particle size distribution (D50 ≈ 0.25–0.28 µm) for optimal brightness and chromatic performance.

  5. Low volatile organic compound (VOC) contribution, supporting compliance with stringent environmental and safety regulations.

Typical Applications Of Xianghai R6658 Titanium Dioxide

  1. Architectural and industrial waterborne paints and coatings.

  2. Automotive basecoat and clearcoat systems requiring high gloss and color fidelity.

  3. Plastic masterbatches for polyolefins, PVC, and engineering thermoplastics.

  4. Printing inks—especially UV-curable and flexographic formulations.

  5. High-performance powder coatings demanding thermal stability and uniform dispersion.
