VANSIL® W-20 Wollastonite

A relatively coarse (1 Hegman fineness) powder grade of wollastonite that can be used as a general purpose extender pigment in most coatings where ultra-fineness is not required. Due to the natural acicular structure and brightness of VANSIL W-20, it can be used as a reinforcing filler in architectural paints where good film reinforcement is required.

A short-needle, high aspect ratio wollastonite (3¼ Hegman fineness). It can be used in architectural coatings where the high aspect ratio yields smooth finish and good film reinforcement.

VANSIL® W-10 Wollastonite

A coarse powder grade of wollastonite (0 Hegman fineness) that can be used in high build coatings where fineness is not a prerequisite. Due to the natural acicular structure and brightness of VANSIL W-10 it can be used as a reinforcing filler in coatings, adhesives, caulks and sealants.
