Aluminium pretreatment and anodizing with Chemetall products will give you perfect surfaces. Excellent adhesion and durable corrosion performance are achieved with Chemetall’s approved products and customized processes. A complete product portfolio is available for all types of aluminium finishing applications, e.g. prior to paint, wet paint and powder-paint processes.

Nowadays, aluminium is all around us in our everyday life – in the buildings we work and live in, in our cars, at leisure. Due to its combination of advantageous properties – like low density, high strength, great formability, easy machinability, corrosion resistance to name but a few – aluminium has become one of the most widely used metals worldwide for many industries.

Pretreatment and anodizing with Chemetall’s specifically designed products and processes for the Architectural and Construction Industries even enhance these great aluminium advantages.

With decades of experience in treating metal substrates, Chemetall is recognized as an environmentally-sound and game-changing technology supplier to the Aluminium Finishing Industry. We are proud of our association with leading companies and associations throughout the world. Everywhere in the world, our aluminum finishing experts work in close partnership with you, our customers, to satisfy your specific requirements for the pre-treatment prior to paint and anodic oxidation of your aluminium surfaces.

Anodizing aluminium

Attractive design and long-lasting corrosion protection: the anodic oxidation – anodizing - offers manifold possibilities for an attractive coloring and a high-performance corrosion protection for your aluminium surfaces. Chemetall products help you optimize your anodizing process, for instance the Gardo® Etch additive for alkaline etching or our Gardo® Seal Series for hot-sealing processes.
