Dispensing with chemicals: Environmentally friendly pretreatment of plastics in the automotive industry
For non-polar plastics, surface activation is essential to ensure the reliable, long-time stable adhesion of adhesive bonds and coatings. The development of Openair-Plasma® technology 20 years ago created a solution which the automotive industry had long been seeking: an alternative to wet-chemical pretreatment processes for material surfaces. WERKSTOFFE (9/2018) reports.
The reason why adhesive or paint does not readily adhere to clean plastic surfaces is generally because the surface energy is too low. A pretreatment with plasma can quickly remedy this problem. The annual magazine KUNSTSTOFF + VERARBEITUNG 2018 reports how Openair-Plasma® satisfies the automotive industry's strict technical and quality requirements.
Through the development of plasma nozzles in 1995, Plasmatreat established an atmospheric pressure plasma technology in manufacturing technology which can be integrated into continuous, fully automated production processes. The WOTECH Special "Basiswissen Prozesskette Oberflächentechnik 2018" (Fundamentals of Surface Technology 2018) describes the process and outlines today's use and future application possibilities.
Chrome-free protection – Plasmatreat in the aluminum industry
There are alternatives to environmentally harmful, energy-intensive pretreatment processes in the aluminum processing industry. The use of atmospheric pressure plasma is a particularly energy-saving option. In a special edition, leading German trade journal for the aluminum industry ALUMINIUM-PRAXIS (6/2018) reports on the benefits and applications of Plasmatreat technologies.
“Bonding technology – new trends and solutions" Plasmatreat CEO Christian Buske gives his view
What solutions does your company offer to new trends in adhesive bonding technology and where do the challenges lie? How do you ensure knowledge transfer to users and what role do services play in your projects? The specialist journal DICHT! (No. 2(6)/2018) asked selective companies to respond to these questions.
Nature as a Role Model – Plasma for lightweight panel production
Innovative solutions are needed to address future strategies such as resource conservation and energy efficiency. By producing large honeycomb panels and using Openair® plasma for surface treatment before painting, panel manufacturer MonoPan Composites supplies high quality components to the commercial vehicle industry. IST (International Surface Technology, 1/2018) has the case study.

“Potential-free surface treatment” - AP plasma ensures sustainable adhesive processes for LED lighting
A leading lighting manufacturer decided to radically change the pretreatment process used prior to bonding his LED industrial lighting. Replacing wet chemical processes with atmospheric pressure plasma proved a very environmentally safe means of increasing the long-term stability of the adhesive bond. The specialist journal DICHT! (No.4/2017) reports on the reasons for and consequences of this 180-degree turn.
Electronics: “Change for the better” - Plasma in the LED lighting adhesion process
Lighting manufacturer Waldmann based in Swabia in Southern Germany decided to radically change his pretreatment process prior to bonding. With the aid of Openair®-Plasma, he increased the surface quality and long-time stability of the adhesive bond in a very environmentally friendly way. Read the case study in the specialist journal “DICHTUNGSTECHNIK 2018 Annual”.
Automotive Engineering: Corrosion protection from the plasma nozzle
When ZF TRW Automotive decided ten years ago to coat a safety-relevant aluminum component with atmospheric pressure plasma to improve corrosion protection, it was a world first. Today the company pretreats over one million parts a year with Plasmatreat’s environmentally friendly plasma jet technology. The specialist journal ALUMINIUM-PRAXIS (10/2017) reports on this successful application.
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.
