Kaolin for Paint & Coatings

In the paint industry, Titanium Dioxide (TiO2) is the most expensive white pigment. If TiO2 particles crowd together (crowding effect), their light-scattering efficiency drops, wasting money.

UT-WHITE acts as a superior TiO2 extender. Its fine, plate-like particles slot in between the TiO2 pigments. This "Spacing Effect" optimizes the distance between pigments, maximizing opacity (hiding power) while allowing you to use less TiO2.

  • Reduce TiO2 usage by 10-20%
  • Improve Scrub Resistance & durability
  • Enhance flow and leveling properties

The TiO2 Spacing Effect

No Kaolin (TiO2 Crowding) Weak Reflection With Kaolin (Optimal Spacing) High Opacity

UT-WHITE platelets act as spacers to maximize pigment efficiency

Performance Characteristics

High Opacity

Ensures an opaque paint film that effectively covers the underlying surface.

2000+ Scrubs

Reinforces the paint film, making it resistant to washing and abrasion.

Cost Savings

Replace 10-20% of expensive Titanium Dioxide (TiO₂) without compromising whiteness.

Recommended Grades

Grades engineered for paint and coatings formulations, extending TiO₂, improving coverage, and enhancing scrub resistance.
