Supreme Premium opacifying and thickening extender for decorative paints

  • Reduced formulation costs
  • TiO2 extension
  • Outstanding opacity
  • Especially effective in high quality matt paints
  • Good color properties

Sourced from our high quality kaolin deposit in Cornwall, UK, Supreme premium kaolin gives multiple benefits in decorative matt wall paints, where it acts as an opacifying extender and a rheology modifier.

TiO2 extender

Supreme is a fine, platy hydrous kaolin which has been engineered to an ultrafine average particle size (0.4µm) to give optimal spacing of titanium dioxide particles. Using Supreme in decorative matt wall paints allows formulators to generate savings of up to 15% TiO2.

Supreme™ has an ultrafine particle shape for optimum TiO2 spacing

Rheology modifier

As well as exceptional opacity, Supreme confers unique rheological properties to paint. This low shear thickening effect enables formulators to reduce thickener requirement, or can be harnessed to improve settling properties and sag resistance. It is particularly beneficial in high quality matt paint formulations, and in high gel strength paints.

Supreme™ provides superior opacity vs. other minerals due to its unique structure
