VANSIL® W-40

Wollastonite

Category:

VANSIL® W-40 Wollastonite is a fine particle (5 Hegman fineness) low aspect ratio grade of wollastonite that can be used as a general-purpose mineral filler in a wide range of paint and coatings.  It is used as a TiO2 spacer and extender.  The naturally high pH of wollastonite helps to buffer latex paints and coatings, which contributes to improved corrosion resistance and weathering.  This also extends in-can stability and prolongs the lifetime of the coating.
