Production Basic Data Of Zinc Oxide Powder Paint Additive:

Features And Functions Of Zinc Oxide Powder Paint Additive

1. Zinc oxide has a small particle size, a large specific surface area, strong adhesion and hiding power, and greatly improves the effectiveness of the coating.

2. The specific gravity of zinc oxide is small, and it is not easy to form a sinking bottom in use or in the final product.

3. Zinc oxide also has a certain role of shielding ultraviolet rays, which can play an anti-aging role in the paint.

Application Of Zinc Oxide Powder Paint Additive

1. As a white pigment in the paint, it also acts as a filler; because its coloring power is smaller than that of titanium dioxide, when a small amount of titanium dioxide is needed for color mixing, zinc oxide can be used in place of titanium dioxide to make the pigment more The volume is convenient, the fine adjustment is easy and accurate, and the color matching sensitivity is reduced.

2. A small amount of zinc oxide is used in resins containing carboxyl groups to improve coating performance; zinc oxide is alkaline and can react with carboxyl groups in the resin to form zinc soap, improve the flexibility and hardness of the coating film, and the coating film It is cleaner than titanium white.

3. zinc oxide powder paint additive promotes the reaction between epoxy groups and carboxyl groups; in epoxy polyester, polyester and other powder coatings, it accelerates the reaction between epoxy groups and carboxyl groups, catalyzes the curing reaction, and shortens the curing time.

4. Zinc oxide as a conductive functional filler; In some industrial applications, antistatic or conductive powder coatings are required. As a metal oxide, zinc oxide powder paint additive has certain conductivity, so it is widely used as a conductive filler in such coatings.

5. Zinc oxide powder paint additive has the function of shielding ultraviolet rays;

 Zinc oxide is an effective and inexpensive white light stabilizer, especially has good protection ability for UV light in the range of 240~380nm. It is often used in powder coatings, especially for outdoor powder coatings, which has good UV shielding ability and can extend the service life of coatings.

6. Zinc oxide has anti-mold sterilization effect;

zinc oxide powder paint additive has strong sterilization ability, and is widely used for sterilization in water-based coatings. It has anti-mold effect in powder coating.
