The migration of moisture in combination with oxygen at the interface of an injection molded plastic-to-metal joint can lead to corrosion and premature adhesive failure of the hybrid component. The innovative Plasma-SealTight® technology aims to combat this issue in the long term. DICHTUNGSTECHNIK JAHRBUCH 2019 (THE YEARBOOK OF SEALING AND GASKET TECHNOLOGIES 2019) describes the process in detail and reports on the outstanding test results.
In search of an environmentally friendly method for optimizing the adhesion of their aluminum housings, lighting manufacturer Waldmann struck lucky when they found Plasmatreat. Instead of solvent-based cleaners and primers, the company now uses Openair-Plasma® to achieve a tight seal and stable adhesive bond for their surface-mounted LED machine lights. The specialist journal WOMAG (10/2018) reports.
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.
