Frequently asked questions (FAQ) about wet painting

Here you will find answers to the most frequently asked questions about wet painting. Discover the advantages, the materials used and much more. Our aim is to provide you with clear and precise information so that you are well informed about the wet coating process. If you have any further questions, please do not hesitate to contact us.

Anodizing is an environmentally friendly process as no toxic chemicals are used and the treated aluminium is fully recyclable. As anodizing is energy-intensive, the electricity mix plays a decisive role in the ecological balance. BWB continuously invests in optimizing the energy efficiency of its plants.

Minor damage can be repaired by re-anodizing or using special repair kits. In the event of major damage, the anodized layer can be completely removed in order to repair the damage mechanically before it is re-anodized.

In addition to mechanical engineering, aviation and medical technology, the electronics, construction and consumer goods industries also benefit from the advantages of anodizing. BWB also creates anodized works of art that explore the limits of the anodizing process.

Yes, the size and shape of the parts can be influenced by the capacity of the anodizing baths and the uniformity of the layer formation.
The BWB has anodized baths up to 22 meters long. The exact product windows for the individual processes can be found in our range of services.

BWB offers a wide range of surface technology processes at 12 locations. Our specialized plants have market-specific certifications for architecture (Qualanod), medical technology (ISO13485) and aviation (EN9100, Nadcap). We also offer exclusive coating processes such as Permalux and Heloxal, which impress with their outstanding properties. These properties are verified in our internal development and test laboratories.

No, anodizing is a process that is used exclusively on aluminum. However, steel can be protected against corrosion by other processes, such as galvanizing or electroplating. You can find an overview of this in our range of services under electroplating processes.
For a visual surface finish, steel elements can be wet-painted, whereby the color can be matched to anodized components.

Anodizing and Anodising are terms that are often used interchangeably and describe an electrochemical process in which a protective oxide layer is created on aluminium surfaces. This process serves both decorative and functional purposes, such as corrosion protection and coloring. Typical layer thicknesses for anodizing are between 5 and 25 micrometres.

Hard anodizing is a special form of anodizing in which a significantly thicker and harder oxide layer is produced. This coating offers improved wear resistance and is mainly used for industrial applications where high demands are placed on material resistance. The layer thicknesses in hard anodizing are typically between 25 and 150 micrometres.

Ematalizing, also known as ematal Anodising, is a special form of anodizing. During ematalization, a particularly compact protective layer is created in an electrolyte containing titanium. Ematal is used when friction is to be minimized by mechanical contact (e.g. in plain bearings), by a flowing medium (e.g. valve bodies and nozzles for gases or liquids) or a combination of these (in pneumatics and hydraulics).
With its plant in Schlieren, BWB has a proven competence center for ematal and hard ematal coatings.

Bilatal Anodising is a special form of anodizing. Bilatal Anodising produces an oxide layer that is characterized by low residual reflection in the UV wave range. In addition to its outstanding optical properties, the Bilatal coating also impresses with its low outgassing behavior and good wear resistance. A Bilatal coating of aluminum components reduces wear and can improve the measurement results of sensitive precision mechanical-optical devices.

The use of suitable alloys is essential for anodizing visible parts. We recommend sampling, as each alloy reacts differently to the anodizing and dyeing process. In the case of aluminium sheets for façade construction, attention should be paid to “anodizing quality for decorative anodization”.

The technical surface properties also depend on the selected alloy. For technical applications, select alloys with very good technical anodizing properties wherever possible. For large quantities or limited anodizing capability of the alloy, we recommend sampling.
