Product Category: VANSIL® Wollastonite
VANSIL® Wollastonite is a high brightness, white calcium metasilicate mineral mined and processed in Upstate New York by Vanderbilt Minerals, LLC. The acicular nature of VANSIL provides superior functionality over isotropic fillers, such as silica and carbonates.
VANSIL® WG
Wollastonite

A relatively coarse particle, high aspect ratio wollastonite. It is used in high build coatings such as texture paints and mastics to improve mud crack resistance and give film reinforcement.

VANSIL® HR-2000
Wollastonite

A short-needle, high aspect ratio wollastonite (0-1 Hegman fineness). It is used in high build coatings such as texture paints and mastics to improve mud crack resistance and give film reinforcement.

VANSIL® HR-1500
Wollastonite

A short-needle, high aspect ratio wollastonite (3¼ Hegman fineness). It is used in high build coatings such as texture paints and mastics to improve mud crack resistance and give film reinforcement.

VANSIL® W-50
Wollastonite

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.

VANSIL® W-40
Wollastonite

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.

VANSIL® W-30
Wollastonite

A medium fineness (4 Hegman fineness) low aspect ratio grade of wollastonite that can be used as a general-purpose mineral filler in a wide range of liquid coatings and powder coatings.  It is used as a TiO2 spacer and extender.

VANSIL® W-20
Wollastonite

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.
