Usage: Used to produce high-grade paints,coatings and other productions and coating intermediates.
Characteristic and function:
1.Small particle size, specific surface area,strong adhesion and hiding power, greatly improve the effectiveness of the coating.
2.The proportion in the product is small, difficult to from precipitates in the process of using or in the final product.
3.It can prevent ultraviolet ray that can prolong coating’s useful life.
