Corrosion protection: Right on target and eco-safe
The use of wet-chemicals for the pretreatment of aluminum surfaces prior to bonding is still one of the most widely used application methods in the industry. But alternatives have long since been available. The German technical journal WOMAG (3/2019) reports on how PlasmaPlus® technology can effectively replace environmentally harmful methods.
Automotive engineering: “Adhesion from the plasma nozzle”
Only a vision just 25 years ago, plasma from the nozzle now sets the standards for the pretreatment of material surfaces prior to bonding in virtually every sector of industry all around the world. Automotive engineering in particular has benefited from the atmospheric pressure plasma process first integrated into series production in the mid-90s. ADHESION Adhesives & Sealants (4/2018) reports.
Safeguarding the quality requirements of painting processes starts with the pretreatment of the material surface. The environmentally friendly, highly effective pretreatment with atmospheric pressure plasma is the method of choice for solvent-free, water-based paint systems. The magazine IST (International Surface Technology No.3.2018) reports.
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.
Press Release: Plasmatreat Academy - A Dialog between Industry and Science
Plasma moves into the center for professional know-how transfer.
As the innovation leader in plasma-based surface treatment Plasmatreat has been sharing its know-how with the industry for 25 years. The newly founded „Plasmatreat Academy” now combines a wide array of educational programs under one roof and with one common goal: facilitating an in-depth dialog with customers, suppliers, science and research.
Activation of Plastics by Openair-Plasma® (2) - Expansion of the application range for various plastics
The treatment with Openair-Plasma® brings about a targeted, site-selective change in surface properties. In industrial applications, this improves adhesion and normally incompatible polymers can be reliably bonded. Dr. Alexander Knospe demonstrates the possibilities of plasma treatment in the plastics industry and provides insights into the function and advantages of this technology
