Wollastonite for Paints And Coatings Industry

Superior wollastonite powder is used in some paint products, replacing Lithopone and part of titanium dioxide as filling agent, which can improve the leveling of the coating. Wollastonite particle shape is a good coating suspension agent, its sediment soft dispersion, can be used as a clean coating enhancement agent. Because of its low oil absorption. It has a high filling capacity and reduces the consumption of adhesive material, thus greatly reducing the cost of coating. Wollastonite alkaline, is very suitable for polyvinyl acetate coating, so that the color material dispersed evenly, it can be applied to the acidic medium of the pigment connected, can also be made into bright color coating, the surface has uniform distribution of performance, spraying performance is good. It can improve the corrosion resistance of steel coating as filling material. In addition to water-based coating, polyvinyl acetal, can also be used for primer, intermediate coating, oil coating, road sign coating, sound insulation coating, refractory coating and so on. It can replace asbestos in bituminous coatings and wollastonite can be used as a reinforcing agent in self-cleaning paints. Wollastonite powder is used in ink industry to replace part of titanium dioxide and lithopone.
