Wollastonite powder is mixed into powder coatings. Since wollastonite has the characteristics of bright white, needle-like particle shape and low oil absorption, it can produce high-quality white and soft and light-colored coatings, improve the toughness and durability of the coatings, and keep the coatings Smooth surface and good gloss, as well as anti-washing and anti-weathering properties, can also reduce the oil absorption of paint and maintain alkalinity, with corrosion resistance. Using wollastonite as a filler or emulsion in paint can get high-quality bright-colored paint with good leveling and anti-aging properties. Pure white wollastonite is a good raw material for high-quality white paint and paint with elegant and soft colors. It is easy to paint, has a smooth surface, and has high weather resistance. Surface-treated fine-grained, high-aspect-ratio wollastonite products have proven to be cost-effective functional fillers widely used in industrial and marine coatings. Strength, increased durability, enhanced adhesion and corrosion resistance. Wollastonite products are also used in house construction, roof tile materials and powder coatings. It can be used as a filler in coatings to reduce the amount of titanium dioxide, and has good anti-aging and anti-radiation effects, as well as good coverage and adhesion.
