Production method Of Coating Grade Zinc Oxide :
It can be used for products such as top-grade paint, coating material and the coating intermediate etc.
Application of Coating Grade Zinc Oxide :
The particle size is small, specific surface is big. There is stronger adhesive force and hiding power, improving the efficiency of the coating greatly.
2. The specific gravity is small, not easily to form the precipitation in use or in the final product.
3. This product also has some functions to shield the ultraviolet ray. It can play the anti-aged function in the coating.
Packing and storage of Coating Grade Zinc Oxide :
This product is packed with plastic-lined and plastic-coated woven bags, 25kg per bag. This product should be keep from breakage, moisture, pollution and contact with acid.
Product quality standards: GB/T 3185-92

Zinc Oxide for Coating
In the coatings industry, with zinc oxide in addition to coloring and hiding power, but also is a preservative in paint and light-emitting agent; In addition, Zinc oxide cellent UV shielding capacity of its anti-aging, such as coating with a more prominent characteristics.
