CORONA & PLASMA TECHNOLOGY:
MODERN TIMES IN SURFACE TREATMENT
Innovations for more efficiency and reliability
Surface technology is facing a radical change: 50 years ago, corona technology upended film extrusion and finishing; today, it is the increasing success of atmospheric pressure plasma that is changing surface technology. Then, electrical corona discharges rendered obsolete many chemical adhesive agents; today, many other chemical pretreatment processes such as the application of primer and top coats are being replaced by plasma surface-modification processes. This is made possible by advances in conventional corona technology towards new atmospheric pressure plasma technologies which can create plasma in various gas atmospheres which in turn can be used to create new surface properties, or to create proven surface properties even more efficiently than before.
Advantages of Plasma Surface Treatment: even thinner layers
Plasma technology strives to allow the application of ever thinner layers onto the material to be treated. When applying liquids to surfaces, the resulting layer typically has a thickness of a few micrometers.
Cut in material leads to stunning cost effectiveness
Taken to the limit, plasma technology can be used to apply nothing more than a molecular monolayer. This means up to 90% cost savings compared to surface coating with a conventional primer or top coat application.

Quality through expertise
In July 2009, the Plasmawerk GmbH was founded to accelerate the transformation of innovations in the field of surface pretreatment into marketable technologies. Experts and innovators of cutting-edge corona technology are offered a place to meet.
Personal relationships with the upper echelon of research institutes ensure a high standard of research and development. In addition, a constant dialog with market drivers allows for maximum customer proximity when developing technical equipment and workflow solutions.
In the last years Plasmawerk presented several pioneering solutions in the field of surface functionalization of web-like material. The world’s first systems were equipped with the technologies and further developed according to customer requirements.
After this phase of product innovation the established mechanical engineering company Neuenhauser Maschinenbau GmbH has become a strategic partner of Plasmawerk Hamburg in 2018 in order to meet the growing demand with good and punctual quality, but still be able to meet customer requirements flexibly at the highest level.
