Atmospheric plasma solutions: High-efficiency plasma cleaning, activation and nanocoating of surfaces

Atmospheric pressure plasma pretreatment is one of the most efficient plasma processes for cleaning, activating or coating plastics, metals, (e.g., aluminum), glass, recycled materials and composite materials.

In comparison to low pressure plasma technology, no special chamber system is required when Openair® plasma technology is used.

During ultrafine cleaning with Openair® plasma (plasma cleaning), surfaces are gently and safely cleaned of release agents and additives and sterilized (plasma sterilization), while plasma activation makes later adhesion of glues and coatings possible. By using the nanocoating PlasmaPlus® (plasma coating), functionalized surface characteristics can also be produced that meet special product requirements.

Openair® plasma solutions – pretreatment under atmospheric conditions: Inline. Cost-effective. Environmentally-friendly.

Plasmatreat has taken on the challenge of replacing other surface treatment processes – e.g., the less-effective corona process – with efficient atmospheric solutions. The Openair® process is a simple, safe and environmentally-friendly technology: Only air, electrical power and the existing production line are required for plasma treatment under normal pressure. As a result, Openair® plasma is in use in almost all areas of industrial manufacturing.

Advantages of Openair® plasma technology compared to other pretreatment processes:

  • High process reliability:
    Openair® plasma technology is distinguished by high fail-safety and process reliability.
  • High cost-effectiveness:
    High process speed, even in multi-shift operation, and lower scrap rates provide high process efficiency. Because it allows for flexible material selection, the Openair® process also facilitates the use of more advantageous materials.
  • High degree of activation:
    Unlike corona treatment, Openair® plasma permits a high degree of activation of the surfaces to be treated.
  • Large process window:
    Openair® plasma permits a large process window: The danger of thermal component damage is extremely low in comparison to flaming.
  • Easy to integrate:
    In contrast to mechanical processes, like roughening and sand or aluminum oxide blasting, Openair® plasma can easily be integrated inline in existing processes.
  • Environmentally friendly:
    The Openair® plasma process makes it possible to treat surfaces with solvent-free and VOC-free methods. Unlike electrochemical processes, such as galvanizing or galvanically-supported pickling and chrome plating, wet chemistry is not required.
