Pre-treatment
Iron phosphate and particularly Zinc phosphating of ferrous metals improves corrosion resistance. Aluminium substrates may require a chromate conversion coating. Aluminium, steel or Zintec surfaces to be coated must be clean and free from grease.
Application
Unused powder can be reclaimed using suitable equipment and recycled through the coating system. Re-coat (overcoating) is not recommended. Powders can be applied by manual or automatic electrostatic spray equipment.
