Every galvanized surface has one final threat which is corrosion. Aquachrome Passi 100 is a trivalent chrome-based passivation chemical engineered specifically for HDG and zinc plated components. It bonds instantly to the surface after quenching, forming a stable, invisible protective layer that locks out white rust and oxidation.
One dip. Lasting defence. Whether you run a high-volume hot dip galvanizing line or treat precision zinc plated parts, Aquachrome Passi 100 delivers consistent, reliable passivation — every batch, every time.
Why galvanizing industry leaders choose Aquachrome Passi 100:
Forms a durable barrier against oxidation and corrosion at the surface level.
Stops white rust from forming on freshly galvanized components. No more surface failures post-dispatch.
Leaves a clean, transparent coating. No streaks. No discoloration. Surface integrity stays intact.
A small amount goes a long way. Low concentration means significantly reduced chemical cost per batch.
Fits seamlessly into your existing galvanizing line. No extra equipment. No workflow changes.
Simple parameters. Consistent results. Aquachrome Passi 100 integrates easily into any galvanizing operation.
