The purpose of plasma 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 Plasma results in good wetting of the material over the surface of the substrate and so improves adhesion.

VacuTEC creates a high frequency electrical discharge under low pressure to treat the surface of various shaped products including profiles, containers, mouldings and extrusions for improving the adhesion of printing inks, glues and coatings.

In the treating chamber a vacuum is built up to between 2 and 12 mbar before an electrical discharge is created through the integrated electrode elements. Treatment cycle times of between 2-120 seconds are normally required and depend on the material and shape of the item to be treated,

The VacuTEC is appreciated for its simplicity of operation, reliability in production and fast process speed.

Treating gasses such as Argon and Oxygen can be applied, but in most cases this is not necessary due to the intense effect created in the VacuTEC.
