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.
