Phosphating
Phosphating is used particularly for components made of steel and iron. Products made of zinc or other non-ferrous metals can also be phosphated. The areas of application of this process are corrosion protection, reduction of wear, adhesion promotion and electrical insulation. Since the phosphate layer produced adheres very well, it is often used as a substrate for coatings.
Chemical preparation/Phosphating
Currently, we offer a chemical treatment with iron phosphate, which prevents oxidation, increases paint adhesion and resistance to environmental influences. The colour of the coating varies according to the weight of the coating, from pale blue in case of a light coat to grey in case of a heavy coat.
Our phosphating workflow
- Corrosion protection in combination with organic coatings such as paints and polymer coatings
- Facilitation of cold forming processes such as wire stretching, pipe stretching or deep drawing
- Corrosion protection in combination with oils and waxes
- Corrosion protection without further treatment
- Improving antifriction properties
- Strong adhesion necessary for further painting or for further application of organic compound solutions
Applications of phosphating
The phosphating procedure usually consists of the following steps:
- Surface cleaning
- Washing
- Surface activation
- Phosphating
- Rinsing
- Neutralising rinsing
- Drying
