Coated aluminium: the importance of pre-treatment process

Pre-treatment is essential for coated aluminium and it’s an important part of the finish production of a protective layer on the aluminium surface. The more usual pre-treatment process is the chemical one with different versions for food packaging, architectural or transport applications. Chemical pre-treatment guarantee the perfect adhesion of coating, an absolute surface cleanliness and absence of odour. Even if this pre-treatment is the most usual, we can have different ways to apply paint on aluminium. The main three processes are powder coating, wet paint and electrophoretic coating. The choice depends on the final use.

Applications of lacquered aluminium

Coated aluminium can have different final use. It’s widely used in automotive and building market. This happens because it’s more resistant to corrosion caused by humid environment than other materials. In addition lacquer emphasizes the aesthetic component of the product. Lacquered aluminium is equally used in food industry because it increases corrosion resistance against acid and salty food, extends products shelf life and it has the ability to withstand the rigours of pasteurisation and sterilisation using retort processes.
