Speciality:
- The small particle size, specific surface area, strong adhesion and hiding power, greatly improving the effectiveness of the coatin
- small proportion of the goods, not easy to form precipitates in use or the final product.
- The goods have a certain shielding ultraviolet radiation, anti-aging role of play in the paint.
