The superior wollastonite powder is used as a filler in paint coating products to replace some lithopone and some titanium dioxide and imported P820, which can improve the leveling of the coating. The particle shape of wollastonite is a good suspension agent for coatings, and its precipitate is soft and dispersed, which can be used as an enhancer for clean coatings. Because of its low oil absorption, there is a high amount of filling, reducing the consumption of adhesive substances, thus greatly reducing the cost of coating. Wollastonite alkaline, spraying performance is good, the surface has a uniform distribution of performance, it can be applied to the acidic medium pigment connected, very suitable for polyvinyl acetate coatings. It is used as a filler to improve the corrosion resistance of the steel coating. Wollastonite is not only used for water-based coatings and polyvinyl formal, but also can be used for primer, intermediate coating, oil coating, road sign coating, sound insulation coating, refractory coating, etc. It can replace asbestos in the leachate paint, and wollastonite can be used as a reinforcement agent in the self-cleaning paint.
