Polsperse Highly dispersible kaolin grade for TiO2 extension in solvent based products

  • Effective TiO2  replacement
  • Gloss control
  • High dispersibility

Polsperse grades are fine and ultrafine, super-dispersible kaolin produced by a high intensity pulverization process. Polsperse grades are specifically designed for use in solvent-based paints and primers. The major advantage is that Polsperse grades disperse rapidly in these paints to a fine Hegman gage value.

PolsperseTM - Fine & Ultrafine super-dispersible kaolin

Polsperse grades are platy hydrous kaolin which has been engineered to be highly dispersible in solvent-based paint to give optimal spacing of titanium dioxide particles and give a smooth surface. Using Polsperse in solvent-based paints allows formulators to generate savings of up to 15% TiO2.

Solvent-based paint film containing a standard hydrous kaolin. Naturally occurring agglomerates are not well dispersed during high shear mixing (HSM).

Solvent-based paint film containing a super dispersible hydrous kaolin. Naturally occurring agglomerates are pulverized during the drying stage. Suitable for HSM dispersion.
