A prerequisite for the adhesion of an adhesive or coating to a surface is wetting. For wetting to take place, the surface energy of the substrate must be greater than that of the coating. In particular, very many plastics have a very small surface energy and are correspondingly difficult to bond. Often the aim of a plasma treatment is to make a surface wettable and bondable. The wettability can easily be tested with test inks. Diener electronic supplies a test ink set with 8 liquids with surface tensions between 30 and 73 (105) mN/m suitable for most practical applications. There is also a set of 23 test inks, with additional gradations between 30 and 73 (105) mN/m.

Plasma systems from Diener electronic have long since established themselves in a wide range of industrial sectors. With the Tretra 320R low-pressure plasma system, you can rely on modern and future-proof cold plasma technology in a vacuum. The chamber volume of approx. 320 litres of this plasma system offers enough space to serve series production / automation. Low pressure plasma treatment is a proven technique for controlled ultra-fine cleaning, adhesion enhancement (activation and etching) and coating of thin films on substrate surfaces. Plasma is generated by applying high-frequency voltage in the vacuum chamber. In the process, the process gas introduced there is ionised. Fields of application: VOC-free cleaning of organic residues Activation before painting, gluing, potting, ... Etching of PTFE, photoresist, oxide layers, ... Super-hydrophobic and -hydrophilic coatings

Plasma systems from Diener electronic have long since established themselves in a wide variety of industrial sectors. With the atmospheric pressure plasma system PlasmaBeam RT, you can rely on modern and future-proof plasma jet technology under atmospheric pressure. Due to the treatment width of 120 mm, substrates can be treated locally with precision. With our new product, the PlasmaBeam RT, there is now the perfect solution for fast, efficient and wide in-line plasma treatment of 2D surfaces. The RT can be perfectly integrated into existing production lines and thus enables the automated cleaning and activation of various components and web-shaped materials. We create the possibility of up to 120 mm wide plasma treatment, with the usual consistent quality and effectiveness of atmospheric pressure plasma systems from Diener electronic.
