Technical cleanliness influences component quality

Particularly in the automotive industry, as well as in medical technology, aviation and the electrical industry, expectations regarding the quality and functionality of components are high. It is therefore important to avoid any possible contamination in production and processing operations. For example, silicones, solvents and other critical substances can cause coating defects in the painting process or damage to components due to contamination.
