Wollastonite - Natural Pigments
Wollastonite is a calcium metasilicate mineral, available in two powder grades of fineness. The relatively high pH (10-11) of wollastonite is particularly useful in maintaining the desired alkaline pH level of water-based paints and preventing early rusting of water-based coatings. Wollastonite is an excellent extender pigment for powder coatings as well as solvent-based and water-based paints.
