Passivation
The passivation of metals is a chemical process that provides a protective layer above metal, which strengths metal protection to corrosion and allows different types of finishings.
Galsup provides several types of trivalent passivations:
White / Blue
Black
Iridiscent
Clear
Sealing
The application of a sealant, combined with the proper passivation, increases the resistance to metal corrosion, and it is applied by requirement.
