Features Of CNNC Taihua R216 Titanium Dioxide

  1. High refractive index for exceptional opacity and hiding power in coatings and plastics.

  2. Excellent dispersibility in both aqueous and solvent-based systems, reducing milling time and energy consumption.

  3. Surface-treated with alumina and silica for enhanced weather resistance and reduced photochemical degradation.

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

  5. Consistent particle size distribution (D50 ≈ 0.25–0.30 µm) ensuring uniform gloss and color development.

Typical Applications Of CNNC Taihua R216 Titanium Dioxide

  1. Architectural and industrial waterborne coatings.

  2. PVC profiles, rigid pipes, and synthetic resin flooring.

  3. Automotive OEM and refinish basecoat/clearcoat systems.

  4. Masterbatches for polyolefins and engineering thermoplastics.

  5. Printing inks requiring high brightness and lightfastness.
