Assembly of the bath: Fill in the tank at 2/3 with tap water, add the quantity of Brugal Galvapas 320, and add tap water up to the requested level. The exact concentration to be discussed with VCD.

Process step: the hot pieces coming out of the galvanizing kettle can be dipped first in the cooling tank and after in passivation bath or directly dipped in the passivation tank with Brugal Galvapas 320 (maximum allowed temperature on the parts 200°C).

Maintenance: by VCD laboratory once a month

Comments:
Dipping hot pieces can produce some vapours.
If the pieces are not hot enough in order to ensure the polymerization, you have to put the pieces in the dryer after passivation (10 min at 60-80 °C).
You have to plan, following the conditions, time for the drying of the passivated pieces at ambient temperature before unloading from the rack.
Equipment – A bath with anti-acid coating, inox steel or plastic.:
