Wollastonite has a bright color, high refractive index (1.63), strong covering power, and low oil absorption rate. It can effectively improve the mechanical strength, corrosion resistance, weather resistance, and heat resistance of coatings and paints, such as washing resistance, weathering resistance, and film cracking resistance. It is a functional filler for building coatings, anti-corrosion coatings, waterproof and fireproof coatings.

Wollastonite can be used to produce high-quality white paint and clear and transparent colored paint; In the interior latex paint system, wollastonite can replace 20% -30% of titanium dioxide in the system without affecting the coating coverage and washability, and increase the pH value of the system while reducing the production cost of the coating.
