VANSIL^® W-50

VANSIL^® W-50 Wollastonite is the finest of the low aspect ratio grades of VANSIL (6+ Hegman fineness).  This grade is suitable for liquid industrial and corrosion resistant coatings, powder coatings and semi-gloss architectural coatings. In powder coatings, this grade is desirable for smoother films and improved gloss.  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.
