Spray Passivation

Application via spray nozzels in a bath (automatic)
Manual possibility, just spray (mist) and passivate
Excellent white rust prevention, long-term protection
No bath control needed

AD Chemicals introduces a unique spray-applied passivation for freshly hot-dip galvanized steel. This Chromium-6 free solution can be applied manually via spray gun or automatically using nozzles, making it a versatile alternative for galvanizers who do not (yet) operate with passivation baths. With this technology, a passivation step can be seamlessly integrated into any galvanizing line — regardless of existing infrastructure.

Traditional passivation methods require a dedicated immersion bath in the quenching or cooling stage. This spray technology provides a solution for galvanizers looking to upgrade their corrosion protection capabilities without major process modifications or investments.

Innovative passivation technology – even without immersion baths

It is especially ideal for:

Smaller galvanizing operations
Retrofit in existing lines
On-demand or localized treatment
No need for bath control
