▣ Phosphate / Phosphate
The metal surface is difficult to bond with paint due to its crystal structure, and it is easily peeled off and rusted even with a slight external impact.
The chemical conversion treatment of metals uses adhesion chemically formulated to the metal surface (iron, zinc, aluminum, etc.) to change the surface of the metal into non-conductive inorganic salts, thereby maintaining the strong physical bond between the metal body and the paint to maintain adhesion. It reinforces and prevents the spread of corrosion in damaged areas of the coating and makes it resistant to material deformation and physical shocks.
※ FEATURE
High Zinc Coating
As a zinc-based treatment agent, it has excellent film forming ability and is widely used in all fields.
Low Zinc Coating
As a pretreatment with phosphoric acid as the main coating component, it is widely used as a treatment agent with iron as an auxiliary component.
Manganese Phosphate
It is a compound treatment agent with manganese as its main ingredient and iron as an auxiliary ingredient.
Calcium Phosphate
Zinc phosphate treatment agent and coating with calcium as an auxiliary ingredient have excellent performance and are widely used for copper sheeting and cold firing.

| AC 20S | 50-55 | 2 | 6 | Spray | It is a tri-cation, low-zinc coating agent suitable for the treatment of steel and zinc surfaces. It is used for car bodies and other parts. It can be used even if some galvanized steel sheets are mixed. By treatment, a dense crystalline phosphate film is formed on the surface, so that the corrosion resistance and the coating film improve durability. |
