Uses
Used in the production of top-grade paint, coating and coating intermediates
Characteristic:
1. Small particle size, large specific surface area, strong adhesion and covering power, greatly improving the efficacy of coating;
2. Small proportion, not easy to precipitate in use or final products;
3. It also has the function of shielding ultraviolet ray, which can play the role of anti-aging in the coating.
