Wash and stain preservation

Pre-treating aluminium

Our wash and stain preservation process involves methods for component cleaning and pre-treatment by washing, staining and conversion coating. We reliably clean semi-finished and finished aluminium products of process media or impurities or remove natural oxide layers in the process. By means of conversion films (passivation) subsequently applied in the process, we achieve exact and defined surface qualities as required, for example, for postprocessing steps such as bonding, welding or painting.
