Effective surface cleaning assumes a key role in coating technology and surface engineering because the standards for surface quality are high, even before the coating process. Fraunhofer IST has developed a powerful yet environmentally friendly water-based cleaning technology.

Substrate cleaning is an important prerequisite for the production of high-quality optics. A fully automated cleaning line was developed especially for this purpose at Fraunhofer IST. Being able to accommodate a wide variety of substrate geometries with extreme flexibility and cost effectiveness was the objective. Particles and organic contaminants are removed from the substrates in ultrasound-assisted cleaning lines operating in a clean room atmosphere.

Plasma discharge in synthetic air.

The use of atmospheric pressure plasma processes for the cleaning of surfaces and the activation of polymer foils, wood and wood-based materials to improve wettability is already widespread in industrial applications.
