High performance calcined kaolins extenders for high PVC decorative matt paints
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.
This means you can offset the amount of TiO2 in your mix, without risking loss of quality.
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 kaolin is particularly effective in high PVC decorative matt paints, where its highly structured particle optimizes light refraction and diffraction. It’s ideal for achieving higher brightness, low yellowness, excellent opacity and hiding power, all while reducing the costs of your raw materials.
