VANSIL® HR-1500 Wollastonite is a high aspect ratio, short needle grade of wollastonite. It is used principally as a mineral filler and reinforcing agent to enhance mechanical strength properties in high build coatings, texture paint, block fillers, joint compounds and adhesives. In high film build coatings, the needle-like shape of VANSIL HR-1500 improves mud crack resistance and sag resistance, while also contributing to peak retention in texture coatings. 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. It is recommended that high aspect ratio grades of VANSIL be added late in process to avoid possible damage to the needle structure from high shear mixing.
