Surface activation using plasma technology
Wherever components will be coated, painted or glued in subsequent steps, selective surface activation of the starting materials is indispensable.
Many materials do not have the required surface tension, such as for printing with water-based inks, for bonding with long-term stability with VOC-free adhesives, or producing material composites.
Openair® plasma activation ensures especially efficient surface modification of plastic, metal, textiles, glass, recycled and composite materials. Surface energy is targeted by the plasma activation and achieved selectively, exactly where it is needed. The result is clearly better wetting capability of the surfaces.
Advantages of Openair® plasma activation:
- High process speed and safety
- Large process window due to homogeneous plasma jet
- Cost-effective, environmentally-friendly surface modification
- Pretreatment without corona effect, no material contact with high voltage
- Robot-controlled inline integration in the manufacturing line
What does surface activation with atmospheric pressure plasma achieve?
Surface activation with Openair® plasma is especially effective when nonpolar materials have to be treated, such as plastics that consist of long-chain polymers. Such nonpolar surfaces are difficult to bond and coat. Because plasma energy selectively modifies the surface tension, these materials can be processed easily and new material combinations can be produced, as in the adhesive bonding process.
