Phosphating agent

Its main function is to form a phosphating film on the metal surface to improve the metal's corrosion resistance, wear resistance and coating adhesion.
The main components in the phosphating agent react chemically with the metal surface to form a phosphating film. This process usually includes the following steps:
Cleaning and activation of the metal surface: The acidic components in the phosphating agent can remove impurities such as oil and rust on the metal surface, and activate the metal surface to increase its reactivity.
Phosphating reaction: Phosphate ions, zinc ions, manganese ions, etc. in the phosphating agent react chemically with the metal surface to form a phosphating film. The main components of the phosphating film are zinc phosphate, manganese phosphate, etc.
Curing and stabilization of the phosphating film: The phosphating film is cured and stabilized at a certain temperature and time to make its performance more stable and reliable.
