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.
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.
