Foshan Nanhai Shuangfu Chemical's Zinc Fluorosilicate is mainly used in :

1. Surface treatment

Zinc Fluorosilicate is used as a surface treatment on metals to improve the corrosion resistance.

It reacts with the surface of the metal to form a protective layer that resists corrosion and enhances the adhesion of coatings.

2. Electroplating

Zinc Fluorosilicate is a source of fluoride ions in the electroplating process, producing a uniform and smooth zinc coating on metal surfaces.

Zinc plating provides excellent corrosion resistance and improves the appearance of the metal.

3. Ceramics

Zinc Fluorosilicate is used as a raw material in the production of ceramics.

It is added to ceramic glazes to improve their hardness, chemical resistance, and glossiness.

4. Glass manufacturing

In glass manufacturing, zinc fluorosilicate is used as a fining agent that helps to remove bubbles and impurities from the glass.

It also improves the clarity and quality of the glass.

5. Catalyst

Zinc Fluorosilicate is used as a catalyst in organic chemical reactions,

particularly in the production of synthetic fibers, pharmaceuticals, and pesticides.

6. Adhesives

Zinc Fluorosilicate augments the adhesive properties of resins and polymers on the surfaces of metals.

When added to adhesives, it enhances the bonding strength and durability.
