Specialty Kaolin
Application:
Polygloss 90 is an ultra –fine particle size, high brightness Kaolin, designed to provide ease of disperation and improved gloss in both aqueous and solvent –borne coating and inks. Polygloss 90 specialty Kaolin contributes to improved opacity through efficient TiO2 spacing. Polygloss 90 can be loaded to higher PVC values than standard extender pigment, without decreasing gloss and with minimal effect on viscosity. Polygloss 90 is used in paints and inks to extend pigment and as a partial replacement for the resin component.
