We are specialist manufacturers of products for the anodised aluminium CHEMICAL POLISHING and ELECTROPOLISHING.

Our range of products BD BRIAL, BD DECAP and BD ELECTRODAL ensures the final finishing for each type of alloy and are adapted to the working conditions of our customers.

Degreasing

Any material that is going to be treated superficially must be clean and free of dirt, particles, oils or any other element. In order to achieve this purpose, there are DEGREASE processes. There are several factors to take into consideration when choosing the degreasing process: the dirt, the material, the applied surface finish or the next step in the process. They are usually differentiated as acid, alkaline or inhibited alkaline formulations.

Desmutting

The process of desmutting or deoxidizing is referred to with various names, including neutralizing. This process eliminates the metals present in the surface that appeared during the preparation processes, while also adjusting the pH of the pieces to an appropriate level prior to the anodizing phase.

 

Without flouride

BD Preventox

Anodizing

During the anodization process, a film of aluminium oxide is added to the surface. This artificial oxide layer provides various benefits, including protection against corrosion and the ability to apply colouring processes.

Sulphuric Acid 98%
Tartaric Acid

BD Anodesc
Oxalic Acid

Organic Dying / Inorganic Dying

One of the best aesthetic properties of anodised aluminium is that it allows the colouring process. This process is possible via various methods: organic colouring, inorganic colouring, electrolytic colouring or interference colouring.

Organic and inorganic colouring allows a wider range of colours and hues that aesthetically enhance the finish of the pieces. Barcelonesa is the exclusive and official distributor for Omya and Heubach, leading companies with a long history of supplying high-quality colourants for the anodising industry. This agreement enables us to distribute their products in Spain, Portugal and North Africa.  Download the Heubach Color Chart.
