In galvanizing, the finish defines the product. Aquachrome Passi 300 is a high chrome content trivalent passivation chemical built for HDG and zinc plated components. It delivers a striking blue bright coating — and keeps surfaces protected long after application.
White rust is the silent failure of every galvanized surface. Aquachrome Passi 300 seals it out completely. One immersion. Deep corrosion protection. A high dilution ratio that reduces cost without touching performance.
Why galvanizing plants choose Aquachrome Passi 300 for critical surface passivation:
Forms a uniform, visually superior blue bright coating on every HDG and zinc plated surface.
High chrome content creates a dense passivation layer — delivering maximum resistance against corrosion.
Seals galvanized surfaces tightly against moisture-induced white rust formation.
Works at just 10–15% dilution. More output per litre. Lower cost per component.
Built on trivalent chrome chemistry, safer for operators, safer for the environment, with no compromise on results.
Consistent passivation starts with precision. Aquachrome Passi 300 integrates directly into your existing galvanizing line.
