When different materials are combined, such as in bonding, laminating or painting, surface tension and surface cleanliness are critically important for reliable adhesion. To achieve good adhesion characteristics, the materials are often brought to a specific necessary processing temperature in the manufacturing process. Generally these are very energy-intensive processes. In contrast, plasma treatment is not only an especially effective method for surface pretreatment, it is also an energy-saving alternative.
The use of Openair® atmospheric pressure plasma makes a definite reduction in operating temperatures possible in many applications. The heating process can usually be shortened or even eliminated completely. The same is true for drying ovens when alternative coating systems (like UV-curing systems) are used.
An example of success in coil coating: By using Openair® plasma cleaning (ultrafine cleaning) and plasma activation, it is possible to use UV-curing paints. The complete system configuration is reduced to 25% of the scope of a conventional system.
Determining surface tension with dyne inks now
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.
Plasmatreat supports digitized manufacturing with its Plasma Control Unit (PCU) and makes numerous controls, regulation, and monitoring functions available to ensure consistently high surface-treatment quality and reproducibility.
VOCs occur when solvents and solvent-containing products are used, and they are harmful to the environment. Nevertheless, manufacturing in many industries still involves pre-treating surfaces with primers, bonding agents or other chemicals that release VOCs. With its Openair-Plasma process, Plasmatreat offers an environmentally friendly alternative.
