Phosphating is a chemical process for treating the surface of steel, where barely soluble metal-phosphate layers are formed on the base material. The layers created are porous, absorbent and suitable as a conversion layer for subsequent powder coating without further treatment. They are also ideal as temporary corrosion protection if subsequently treated with oil, water or passivation.

Main areas of application and advantages

  • Temporary corrosion protection for steel, which is to be stored for a limited period before further treatment
  • Good promotion of adhesion for subsequent colour coating
  • Improves the sliding properties with cold forming steel
  • Electrical insulation
