Phosphating Processes

Phosphating Processes

Pretreatment systems

Painted or powder-coated surfaces require high-performance iron, zinc phosphate coatings or no-rinse systems.

Their function is:

  1. To remove dirt and greases from the metal surface.
  2. By means of phosphate coatings, to form a firmly adhering layer that allows paint or powder coatings to adhere firmly and hence prevents infiltration by corrosive media.
  3. By the application of a conversion layer to ensure optimum adhesion conditions for subsequent paint coats.

The ultrafine to coarse crystalline single-crystal and mixed crystal structures of the phosphate coatings produced by chemical reactions can be additionally protected by passivation and oil emulsions. With our product lines  SURFASIT® , SURFACOTE® and SURFASEAL®, we cover the area of paint preparation perfectly.
