In most applications where the corrosion resistance of finished workpieces must be especially high, conversion coatings are applied using PHOSPHAX ZN zinc phosphate .
This approach is widely used in the automotive industry and in certain sectors of the appliance and electronics industries. Similarly, zinc phosphating is often specified by the armed services, especially for equipment that may be exposed to severe environments.
Moreover, many operations using electrocoating or powder coatings, particularly when a one-coat finish will be exposed to the weather, pretreat workpieces with PHOSPHAX ZN zinc phosphate.
TECHNICAL APPLICATIONS OF PHOSPHAX ZN ZINC PHOSPHATING:

• Zinc Phosphating Prior to Powder Coating 
• Zinc Phosphating Prior to Oiling / Lubricating
• Zinc Phosphating Prior to Wire Drawing
• Zinc Phosphating Prior to Tube Drawing
