Openair® plasma activation: high-efficiency surface activation, targeted, selective, environmentally friendly and with long-term stability

Wherever components will be coated, painted or glued in subsequent steps, selective surface activation of the starting materials is indispensable. Many materials require surface modifications, 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 clearlybetter wetting capability of the surfaces.

Determination of the surface tension with test inks shows:

With low surface tension, wetting is impossible. After surface modification using Openair® plasma activation, the material surface has significantly better wetting capability.

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.

Openair®Plasma activation: plasma surface activation & surface modification

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

Plasma Instead of Flame

Peguform pretreats the instrument panels for Audi Q5 off-road vehicles with Openair® plasma instead of the usual flame processing. The selectively applied “cold” plasma jet eliminates the need for masking, while simultaneously protecting the plastic from overheating
