Polestar

Polestar™ High performance calcined kaolins extenders for high PVC decorative matt paints

  • Higher TiO2 reduction
  • Higher brightness, low yellowness
  • Excellent opacity and hiding power
  • Reduced raw material costs

PoleStar™ calcined kaolin aluminum silicate extenders have been specifically designed to allow reduction of the titanium dioxide content in high PVC decorative matt paints, without loss of opacity or hiding power.

The calcination process transforms platy natural kaolin, a natural aluminum silicate, into a highly structured particle that is ideal for improving coating opacity. The structure of the particle increases and optimizes refraction and diffraction of light passing through the coating. This improves the light scattering properties, reducing the interaction of light with the substrate beneath.

Polestar™ is particularly effective in high PVC decorative matt paints.
