What is zinc phosphating?
Zinc phosphating is a surface conversion treatment used before painting or coating steel parts. It creates a phosphate layer that improves adhesion and helps protect against corrosion in downstream service environments.
Typical Zinc Phosphating Process
- Cleaning and degreasing
- Surface activation
- Zinc phosphate treatment bath
- Rinsing and neutralisation
- Drying and inspection
Where It Is Commonly Used
Zinc phosphating is widely used for automotive and industrial components that require paint-ready surfaces with better adhesion consistency.
Process design should consider base material, paint system, and corrosion exposure target.
