PHOSPHATING - ZNP- 54
- Phosphating is a chemical surface treatment process used to prepare metal surfaces for coating or painting, improve corrosion resistance, and enhance adhesion. It involves the application of a phosphate chemical solution to create a thin, adherent layer of crystalline phosphate on the metal\'s surface. This layer provides a good base for subsequent coatings and improves durability.
* Types of Phosphating
1. Zinc Phosphating
- Provides excellent corrosion resistance.
- Commonly used in automotive and heavy machinery industries.
2. Iron Phosphating
- Primarily used as a pre-treatment for painting.
- Less corrosion-resistant than zinc phosphating.
3. Manganese Phosphating
- Known for wear resistance and anti-galling properties.
- Often used in applications involving friction, such as gears or bearings. # Phosphating Chemical Manufacturer.
