It is used to prevent galling of threaded components made from carbon and low alloy steels. It may also be used as a pre-treatment prior to application of oil, paint or dry film lubricant finish.
- Enhances coating adhesion and improves the corrosion resistance of the coating system.
- Usage on threaded components.
- Oil dipping after phosphating provides reasonable corrosion protection.
- Without further treatment (e.g. oil dip or painting) Zinc Phosphate coating provides only moderate corrosion protection.
