Wollastonite Usage

1. This product can be used as a body pigment and extender in the coating industry. Because it can increase the bright color of white paint, and can maintain this color tone for a long time.

2. The needle crystal of this product makes it a good safe agent for coatings and can improve the leveling of the coating.

3. The particle shape of the product makes it a good suspending agent for the coating, making the precipitation of the paint soft and easy to disperse. It can be used as a reinforcing agent in self-cleaning coatings.

4. This product is very alkaline, very suitable for polyvinyl acetate coating, so that the color pigment dispersion is uniform. Wollastonite also has improved corrosion resistance of metallic paints. In addition to waterborne coatings, it can also be used in primers, intermediate coatings, oil coatings, road marking coatings, etc., and can replace asbestos in asphalt coatings. It can partially replace titanium dioxide in latex paint without reducing whiteness and hiding power.

5. This product can also be used in metallurgy, ceramics, welding electrodes, plastics, rubber and other industries.
