Spray Passivation

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
