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.
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.

Put Openair-Plasma® to the test with our rental and test systems.
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.
Plasmatreat supports digitized manufacturing with its Plasma Control Unit (PCU) and makes numerous controls, regulation, and monitoring functions available to ensure consistently high surface-treatment quality and reproducibility.
VOCs occur when solvents and solvent-containing products are used, and they are harmful to the environment. Nevertheless, manufacturing in many industries still involves pre-treating surfaces with primers, bonding agents or other chemicals that release VOCs. With its Openair-Plasma process, Plasmatreat offers an environmentally friendly alternative.
In addition to the Openair-Plasma Systems for surface treatment Plasmatreat GmbH also offers individual production cells with automated solutions to ensure seamless integration in the production lines. Plasma Treatment Units (PTU) are tailored to the customer's technical processes and are equipped with various operating options. Here Plasmatreat offers the solution of coordinated process automation combining efficient surface treatment and a perfectly coordinated handling of assemblies and components.
Plasmatreat plans to get more involved in the disinfection industry by providing solutions for disinfecting protective clothing during the current corona crisis.
