Titania-coatings for medical technology

Titania is a biological harmless and chemical stable material. It is used in various fields, e.g. medical engineering and catalysis. The special property of titania, in addition to the excellent biocompatibility, is the photocatalytic effect (by stimulation of light a substance is decomposed).

Titania coatings are all-rounders. They can be used in medical engineering to coat hip implants, bone screws, dental implants etc. or for medical equipment like scalpels, tweezers, pliers and wound dressings. The reason therefore is a high biocompatibility and a good growth of tissue on the implants.

Furthermore they can be used as antibacterial coatings on surfaces in Life Science due to the photocatalytic effect. Based on years of overuse of antibiotics and the resulting immunization such surfaces play an important role in order to avoid infections. Examples are the coating of medical surfaces in hospitals or doctors’ offices. Even in the private sector antibacterial coatings on door handles, light switches, kitchen surfaces or in the sanitary area play an important role.

Titania surfaces are also used for catalysis of water and can serve as self-cleaning surfaces due to their superhydrophilicity. The peculiarity of plasma-coated titania surfaces is that their effects are present in visible light. Conventional coating show their effects only under UV light or, by elaborate doping, under visible light.

Plasmatreat succeeded in applying titania coatings on surfaces by using Openair® plasma while contributing to the research & development of hygiene and medical technology.

The new DIN 2304: Opportunities for industrial bonding processes and surface treatment

When a bonding process not keeps it´s promise the cause is supposed to be the adhesive. However, in the meantime it has become clear that the main fault is not the material in industrial bonds, but the particular application and errors in the surface pretreatment. The announced DIN 2304 is going to reference on these issues.

The key concept of ISO 9001 is the mastery of processes through a comprehensive quality management. Since bonding is supposed to be a “special process” due to no non-destructive testing technology DIN 2304 contributes on the one hand to the image of bonding processes itself and on the other hand optimizes the confidence that customers and clients have in bonding processes. DIN 2304 is industry-independent and focuses among others on the quality of adhesion processes and on the quality of surfaces to be utilized.

In recent years it has been shown that Openair® plasma pretreatment leads to an optimal adhesion in subsequent bonding processes of different materials while simultaneously ensuring a clear quality assurance. At this year’s tradeshow “Bondexpo 2015” in Stuttgart, Germany it clearly showed that DIN 2304 found it´s way to the forefront. The expectations of the users are positive.

Electromobility in automotive industry

Electromobility, networked and automated driving are the drivers of innovation in the automotive industry. The German automotive industry is pushing the development of electric mobility with great commitment because climate change, the increasing scarcity of fossil fuels and an increased need for mobility by growing population require new solutions and alternative drive systems. Electrified vehicles can make a substantial contribution to environmental protection and to reducing emissions. Therefore, they are an integral part of the diversification strategy of the German manufacturers and suppliers.

The electrification of vehicles is becoming increasingly important and supports the development of the entire system of electromobility. Within this system electric vehicles of plug-in hybrids, range extender vehicles, fuel cell and battery electric vehicles are linked to the energy system and the transport system.

The consequences for quality and quantity of new modules are unforeseeable. As a matter of fact, the production of these units have to be maxed out both price and technology. Aluminum, plastics and especially bioplastics will be the target materials of the future. For the processing of materials optimum bonding technology must be ensured. Adhesives and Sealants require a clean and active surface.

Other components require a functional layer: the AntiCorr® coating technology carries a corrosion inhibiting layer on different metals so that they are protected against corrosion and then glued in subsequent processes.

First-opening-protection available for self-adhesive labels

Modern packaging take on new responsibilities by the advent of new technologies and materials. Fighting against product piracy or protection from improper use are examples that show requirements. Self-adhesive labels are more and more used as an effective first-opening protection. The pharmaceutical industry aims for safety in cartons – the chemical industry even more.

An example for screw caps:
By pretreatment with Openair® plasma the labels sticks on small diameters and tight radii. Even critical areas at the beginning and end label stick optimally. The label sits absolutely tamperproof.

The mechanical and electrical integration of the system by Plasmatreat is simple: The pretreatment of closures happening OFF-Line or in-line, directly and as part of the labeling. The pretreatment of the surface is thus part of the process and offers product and customer safety.

Improvement of adhesion of UV inks on glass by plasma

After a long research and development time the adhesion of UV-curing inks on glass by digital printing can now be improved. For this purpose, the glass first gets cleaned by Openair® plasma so that the surface is pre-treated for a subsequent PlasmaPlus® coating. Since the coating is transparent it does not affect the transparency of the glass. The glass can now be printed as usual. The consistency and quality of the ink adhesion was assessed by different studies with a proven record of success.

We have prepared a limited number of 10x30cm samples for you. If you are interested and need any further information please contact Mr. Buser.

Plasma for final packaging – ice cream and frozen foods securely packaged

Activation and pretreatment of the longitudinal seam of laminated and metallized cartons is today state-of-the-art for folding carton manufacturers. Folding box manufacturers around the world are using the pretreatment technology of Plasmatreat to guarantee the adhesion of adhesive bonds. The final packaging takes place where the products are produced and finally packed into cartons or other package. Particular requirements are applied to frozen products when demanding a safe bond during the final packaging. The bonding area at the loading and removal opening (site flaps) of the package need to be as secure and in the same condition as the longitudinal seam. Therefore, the adhesive tabs are being pretreated by atmospheric plasma within the packaging machine. Depending on the style and structure of the packaging there are up to 3 areas that need to be treated in order to seal the packaging safely.

Packaging machines either work intermittent or continuously with capacities of up to 300 packages per minute. The first Plasmatreat systems are now installed at the end packaging manufacturers. The adhesion to the closing flaps (side flaps) were successfully improved.

Plasmatreat at Glasstec 2014 in Düsseldorf, Germany

Experience the power of plasma at Glasstec in Düsseldorf, Germany. Plasmatreat will present solutions for glass surfaces for the first time. For example, selective or full-surface PlasmaPlus® coatings result in new surface characteristics. Reflected solar radiation (glare) from solar modules can be reduced so that more light beam can be absorbed. Moreover, an adhesion-promoting layer can prepare the surface for a stable and long-time bonding. This is especially important when bonding spacers. The stainless steel diffusion barrier must be reliably bonded so that it is protected against corrosion and moisture ingress.

Bring your own glass sample and get it plasma treated LIVE at our booth G66 in hall 11. Experience the effects of plasma on your surface.

Ask for your personal meeting with our specialists. We looking forward to meeting you.
