VANSIL^® W-20

VANSIL^® W-20 Wollastonite is a relatively coarse (1 Hegman fineness) low aspect ratio grade of wollastonite that can be used as a general purpose extender pigment where ultra-fineness is not required such as texture paints and block fillers. 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.
