Corona Treatment of Sheets and Plates

The purpose of surface treatment of polymer based materials is to increase surface wettability through electrical discharge. The low surface energy of polymer based substrates often leads to poor adhesion of inks, glues and coatings. To obtain optimum adhesion, it is necessary to increase the surface energy of the substrate to just above that of the material to be applied. Corona treatment results in improved surface adhesion properties.

Treatment of sheets and plates for this application may vary from 50 mm to 2000 mm, which gives the customer treatment flexibility of small and large plates. SheetTEC can be installed as a stand-alone unit or with a conveyor system for integration into existing production lines. SheetTEC is available as a single or double-sided surface treatment system.

SheetTEC is equipped with metal electrodes for the optimized treatment of non conductive polymer materials. As an option Ceramic electrodes are available to allow treatment of conductive surfaces such as stainless steel, aluminum, and others. Thanks to the high voltage technology developed by Tantec it is possible to treat sheets over the edges and even sheets where the edges are slightly bent.

The processing speed of the sheets may vary between 0.5 m and 10 Mtr. / Min.

SheetTEC ensures uniform treatment of boards up to 50 mm in thickness.
