This process consists of converting metal surfaces into surfaces that do not have metallic properties. Applications: - Treatment of the metal surfaces so that they can be better prepared for subsequent treatments - Improved resistance to corrosion - Treatment of the metal surfaces for cold extrusion and/or grinding The phosphate coating process consists of 3 elements: - Manganese acts as an anti-scuff - Zinc acts as a paint base - Micro phosphate coating acts as an anchoring base for rubber to metal bonding
