The purpose of corona 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. Surface Treatment with Corona results in good wetting of the material over the surface of the substrate and so improves adhesion. The Dyne Technology supplied SpotTEC 3D corona treater unit creates a high voltage, low frequency corona discharge to treat the surface of 3-dimensional moulded or extruded plastic parts, profiles, webs, containers, etc. An airflow presses the corona discharge towards the substrate to be treated and a counter electrode is not necessary. The electrical discharge creates the necessary functional polar groups on the polymer surface, which promotes adhesion and wettability to printing inks and adhesives.

The SpotTEC corona treating unit gives a process engineer flexibility to tailor a surface treatment system, which can be integrated into existing production processes.

The SpotTEC corona treatment unit is available in two versions, HP-S with a single electrode and HP-D with a double electrode.
