Features Of Jinhai R6668 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 water-based and solvent-based formulations.

  3. Low oil absorption (≤18 g/100g) enabling high loading capacity and improved rheology control in coatings and inks.

  4. Consistent particle size distribution (D50 ≈ 0.25–0.28 µm) for optimal brightness, gloss retention, and UV scattering efficiency.

  5. Low volatile organic compound (VOC) contribution and APEO-free, supporting compliance with global environmental and safety regulations.

Typical Applications Of Jinhai R6668 Titanium Dioxide

  1. Architectural and industrial waterborne coatings requiring high whiteness and weather resistance.

  2. Paper coating and filling applications where brightness, smoothness, and printability are critical.

  3. Plastic masterbatches for rigid PVC, polyolefins, and engineering resins demanding thermal stability and color consistency.

  4. Offset and flexographic inks requiring fine dispersion, low grit, and high tinting strength.

  5. Adhesives and sealants where non-yellowing performance and pH-neutral compatibility are essential.
