The reactive species of the plasma enables metal and polymer surfaces to be thoroughly fine-cleaned without the use of chemicals - and there is no harm to the environment.
Impurities on surfaces, such as lubricant on films, release agents on molded parts or fine coatings of oily dirt on metal, act as a barrier and prevent the applied material from bonding properly. So the ideal surface has to be free of impurities and have good wettability.
Manufacturing processes often leave fine organic residue on surfaces. Plasma ultra-fine cleaning gets rid of the residue. The energy input splits the organic compounds, transforms them to the gas phase and sucks them into the exhaust system. It is a dry chemical process, allowing a coating to be applied immediately.
