Description: Wollastonite has bright color and high reflectivity, which could be suitable for the production of high-quality white paints and clear transparent paints.wollastonite is a good additive with higher fraction of color coverage and homogeneous distribution. Based on its UV resistance, it is widely used in interior wall paints, exterior wall paints, special paint (especially fireproof paint) and latex paints. Wollastonite powder which can partly replace titanium dioxide to produce paint coating can not only improve the color of products, improve the gloss of the paint, enhance the anti-tensile ability of the paint, reduce the crack, but also can reduce the oil absorption and enhance the anti-corrosion ability. The finer particle size, higher whiteness and pH value can greatly improve the color and coating property of the paints, which can be helpful to produce anticorrosive coating for metal equipment such as steel pieces. Wollastonite can also be used as the filler of paint coating to improve the physical and chemical properties, durability and weather resistance and reduce the fracture and aging of the paint. The quality requirements of wollastonite in paint coatings are: SiO2 49%min, CaO 45%min, Fe2O3 0.2%, 325 mesh, mineral powder oil absorption amount is 20-25g/100g, water soluble matter 0.5%, water extraction pH value is 7-9, whiteness 90%.
