Features Of Huiyun R-666 Titanium Dioxide

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

  2. Optimized particle size distribution ensuring excellent dispersion stability in aqueous and solvent-based formulations.

  3. Surface-treated with silica and alumina for enhanced weather resistance and reduced photocatalytic activity.

  4. Low oil absorption (14–16 g/100g) enabling high loading capacity and improved formulation rheology.

  5. Consistent batch-to-batch performance validated by ISO 9001-certified manufacturing control.

Typical Applications Of Huiyun R-666 Titanium Dioxide

  1. Architectural and industrial coatings requiring durable whiteness and gloss retention.

  2. Plastic masterbatches for polyolefins, PVC, and engineering resins.

  3. Printing inks—including offset, flexographic, and gravure—where color strength and print clarity are critical.

  4. High-performance powder coatings demanding thermal stability and surface smoothness.

  5. Specialty elastomers and synthetic rubber compounds requiring UV shielding without degradation.
