  • CF4 - plasma treatments

    CF 4 is a process gas frequently used for coating processes by means of plasma polymerisation. It is used for the generation of fluorinated surfaces, in particular for epilamisation, i.e. the production of a perfluorinated surface. By means of plasma polymerisation, PTFE surfaces can be made from CF4 polymers.
