Omega italy is able to supply all kinds of powder coating and anodizing for aluminium profiles, including sublimation wood effect. Our important partnerships allow us to cover every request and to give, if requested, the various certifications.
Anodic oxidation is a process through which a protective layer of aluminium oxide forms on the surface of the aluminium profile protecting it from corrosion. The layers of anodic oxide originate from the direct transformation of the base metal, therefore their properties depend on those of the metal itself.
Omega italy can propose:
|for interior architecture||Class 5||thickness µm 5|
|Class 10||thickness µm 10|
|For external applications||Class 15||thickness µm 15|
|Class 20||thickness µm 20|
|Class 25||thickness µm 25|
Before the painting, the aluminium can be pre-treated in two ways:
• Through anodic oxidation pre-treatment. • Through no-rinse, chrome-free pre-treatment.
The painting with oxidation pre-treatment has been specially developed for aluminium, being this alloy very resistant to corrosion caused by chemical and atmospheric agents. It consists in the production of an anodic oxide developed to fix the adjacent layers of heat-polymerized outdoor powder paint. This system combines the extremely high resistance of the anodic layer with a film of polyester powder paint. It is indicated for marine environments, where aluminium is frequently exposed to filiform corrosion.
The painting with no-rinse, chrome-free pre-treatment offers an excellent adhesion base and a protective coat before the powder painting. This process can be compared to the chromic treatment. A high resistance to corrosion can be associated with powder painting, thus allowing its use in many applicative areas.
