POLYMER COMPOSITES 2019 – Plasma optimizes adhesive processes in the automotive industry
POLYMER COMPOSITES 2019, the international conference organized by the Czech "Association for Technical Support and Promotion of Polymer Composites", focuses this year on the latest technologies for plastic composites and trends in the manufacturing and processing of these materials. One catalogue entry describes how Openair-Plasma® has significantly improved adhesion processes for plastic surfaces for users in the automotive industry.
Coil Coating: Plasma replaces chemical fine cleaning
For the past 12 years, Openair-Plasma® has enabled a leading solar shading manufacturer to avoid using any chemicals whatsoever for fine cleaning their aluminum strips before coating, and so set an example in environment responsibility. Leading German trade paper for the aluminum industry ALUMINIUM-PRAXIS contains a detailed report in its special magazine edition "Energie- und Ressourceneffizienz in der Aluminiumindustrie" (01.2019) (Energy and resource efficiency in the aluminum industry).
In medical engineering it is particularly important to be able to selectively alter the surface characteristics of plastic components. Openair-Plasma® and PlasmaPlus® enable pretreatments to be applied to precisely defined areas. The plastics processing magazine PLASTVERARBEITER reports on applications and possibilities in its special issue MEDPLAST 2019.
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.
