01 / Product brief
OEM-Validated Zinc Phosphate for Automotive
Standard-temperature zinc phosphating chemistry producing 4–10 g/m² on ferrous metals at 40–60°C. Seven-stage immersion or spray-immersion process yields a hopeite/phosphophyllite crystal structure optimised for OEM paint adhesion and corrosion performance under primer and topcoat systems.
Validated against major Indian and international OEM paint adhesion and salt-spray specifications. Available in a chromium-free passivation-compatible version for EU ELV supply chains — no change to the phosphating stage required.
