Plasma, an ionized form of gas, due to its high electrical conductivity and chemical reactivity enables to modify the physical attributes of surfaces. Metal, plastic and bio-materials treated with plasma, which in regular conditions show nonpolar properties, obtain a homogeneous finish and adhesive features to enhance the following coating process. By reducing pressure, temperature-sensitive surfaces can be treated with plasma without damage.
In order to prevent potential contamination, further processing is carried out in ISO class 7 clean room. Purity of activated surfaces can be additionally controlled by using a microscope. Low pressure plasma treatment effects:
- Activation of polymer chains
- Polymerisation of suitable monomers
- Reduction of oxide layers
Typical application areas:
