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.
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.
Advantages of Openair-Plasma® activation:
High process speed and safety
Large process window due to homogeneous plasma jet
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
New Research and Testing Equipment for Highly Technical Surface Treatment
Plasmatreat constantly faces shifting demands as a result of new ideas, regulations, and standards. Customers are increasingly approaching the company with unique and innovative project requests. Consequently, the capacities of the technology and research center will now be expanded to include a class-6 cleanroom.
