Zinc phosphating
Zinc phosphating for improved durability of coatings
Zinc phosphating is a surface treatment process used to protect metal surfaces from corrosion and improve the adhesion of subsequent coatings such as paints, varnishes or powder coatings.
It is a functional coating that also provides good corrosion protection, but compared to galvanizing, the focus is more on coating adhesion.
- good corrosion resistance
- Excellent adhesion of coatings
- flexible choice of materials
- Uniform coating on complex or uneven surfaces
- Cost efficiency
The choice between zinc phosphating and other finishing processes, such as galvanizing, depends on the specific requirements of the application, the desired properties of the coated workpieces and the environmental conditions.
Areas of application
- Adhesion of protective and decorative coatings
- good temporary corrosion protection for long delivery routes
- electrical isolation
- Friction and wear reduction
