Phosphating Chemicals

Listing ID #3691395

Phosphating is a process of depositing a conversion coating onto steel and galvanized steel to prepare the surface to receive a liquid, powder, or electrodeposited coating. The phosphate deposit is referred to as a conversion coating because it converts the surface of the virgin steel (no oxide present) to a roughened amorphous or crystalline phosphate composite. The Phosphate coating used as a pretreatment prior to paint application is essentially of two types-Zinc Phosphate and Iron Phosphate. We offer zinc phosphating chemicals like PHOSCOAT TZ and PHOSCOAT XLZ, based on the process conditions at customer's end. PHOSCOAT I is the Iron Phosphate formulation that we supply. Zinc Phopshate has excellent chemical resistance, whereas Iron Phosphate is used for components used for interior service and has the advantage of excellent mechanical properties of applied paint.
