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.
