Plasma in lightweight construction
Plasma treatment results in a significant improvement in adhesion in lightweight construction, especially for materials with low surface energy.
Plasma in the automotive industry has meanwhile proven itself and has already become standard in many places. This is mainly due to the fact that improved quality and process reliability are of paramount importance here. By integrating plasma technology into the automotive industry, process speeds can be increased while maintaining consistently high quality. For example, modern composite materials such as CFRP (fibre-reinforced plastic) are bonded with the aid of plasma. Long-term stable adhesive bonds can be achieved by pretreatment with plasma. Read our application example with Roding Automobile.
Plastics are usually characterized by inert surfaces with surface energies between 20 and 40 mN/m. In order to wet a surface, however, the surface energy of the polymer must exceed the one of the paint or the adhesive. This condition can be achieved through a plasma treatment of the surface and is called "activation“ in plasma technology.
