Pretreatment: Activation of surfaces individually and specific to the application

Plasma technology is suitable for activating surface materials such as plastic, metal, fabric or even glass.

Wherever in later steps surfaces are to be coated, painted or adhesively bonded, selective activation of the starting materials is imperative.

Short film: Activating surfaces with plasma

The determination of surface tension using test inks shows that: when surface tension is low no wetting is possible; following activation by Openair® plasma the whole surface can be wetted. Play video (You need Windows Media Player to view the video clip)

What is the effect of activating surfaces with plasma?

Surface treatment with plasma is particularly effective, for example, in the activation of plastic surfaces because plastics consist of long polymer chains. These non-polar surfaces are difficult to bond and coat. Due to the structural modification, however, the surfaces may now become more readily processable and in bonding processes new materials can be joined. 

Advantages of activation with plasma
High process speed and reliability Great process latitude due to the homogeneous plasma beam Low-cost, environmentally friendly pretreatment Pretreatment without corona effect; the material does not come into contact with high voltages
