We operate a large capacity 3 Metre Diameter automated phosphate service with a 3 stage wash cycle:

  • hot washing with a phosphate solution
  • hot rinsing
  • hot passivation solution

As well as the large 3 Metre Diameter capacity basket we can undertake pre-treatment of much larger items using the lance attachment.
Phosphate Solution: The phosphate solution used is designed for the conversion of iron, steel, aluminium and zinc surfaces to a lightweight Zirconium phosphate coating.

Hot Rinsing: The hot rinsing is a water solution with synergic detergent additives.

Passivation Solution: The final rinse contains a highly concentrated non-chromated solution which provides a sealing action that improves paint adhesion and extends resistance to humidity and salt spray.


Zirconium Phosphate is a, natural, single stage clean and pre-treatment technology,
which has been designed as a clean and pre-treatment prior to application of organic coatings such as:

  • Wet paint of all types
  • Powder paint – electrostatic spray, fluidised bed
  • Plastic coatings such as PVC and polyolefins

Zirconium Phosphate is a realistic environmentally friendly alternative to:

  • Chrome conversion coats on Aluminium and Zinc
  • Zinc phosphating on steel and galvanized
  • Iron phosphating on steel , Aluminium and galvanized

Zirconium Phosphate offers excellent quality performance and will achieve 1000 hours plus on steel and at least 3000 hours on aluminium (neutral salt spray)
