Hydrous Kaolin

3 pots of paint with brushes lying on the top

Product Overview


KaMin’s ASP® range of hydrous kaolin is comprised of a range of options for extending titanium dioxide and other pigments in both aqueous and non-aqueous systems. ASP® is a versatile product offering that can be used in coatings, inks, rubber, plastics, adhesives and sealants.

Most grades have high brightness and offer solutions for high gloss and semi-gloss coatings. Pulverization ensures a narrow particle size distribution with a very fine average. Certain products are pre-treated with dispersants making dispersion easy. Spray-dried grades allow easy handling and low dusting.
