Passivation as a flexible multi-function solution
Passivation is a chemical conversion of the metal that prevents external agents from attacking the aluminium, thereby preventing corrosion and prolonging the life of the product. It is a process optimal for interior components – not those in direct contact with the external environment – and for responding to the need to maintain the conductivity of aluminium.

After desmutting, when cleaning and the removal of residues occurs, the application is processed with liquid dipping or spraying, followed by curing. Passivation is not only a final treatment, it can also be used as a pre-treatment for other processes, such as powder coating or wet painting.
As a conversion coating, passivation can be used both for aluminium and for other base materials, according to the continuously changing requirements of applications and industries.
Passivation’s benefits include corrosion protection – it meets many of the automotive industry’s required specifications – and as an adhesion layer to support bonding between two materials.
Indeed, a passivation layer can provide other machining, glueing or welding processes with a high-quality environment that allows you can speed up processing times.
