With low-energy surfaces such as silicone, polypropylene or Teflon, a strong increase in surface energy is achieved after surface activation with the piezobrush PZ2 handheld plasma device.
With relyon plasma plasma technology, the surface treatment of various materials for further processing is possible quickly and easily. With the surface treatment you can thoroughly clean and disinfect surfaces, strengthen the adhesion of adhesives and lacquers and thus improve the overall result. All this is very environmentally friendly as it does not require any chemicals and does not generate any running costs.
Surface energy Determination of surface energy by means of test inks and contact angle measurement, enhancement through plasma treatment Wettability is of major importance for all kinds of surface treatments like printing, varnishing and gluing. It describes the behaviour of liquids on solid surfaces which is dependent on the surface tension of the liquid and […]
Plastics are usually characterized by inert surfaces with surface energies between 20 and 40 mN/m. In order to wet a surface, however, the surface energy of the polymer must exceed the one of the paint or the adhesive. This condition can be achieved through a plasma treatment of the surface and is called “activation“ in plasma technology.
The high temperatures which are reached in most plasma applications make many users wonder about process safety, especially when highly sensitive materials are treated. This article addresses open questions concerning temperature and heat conduction during plasma applications and cites critical examples which substantiate the suitability of plasma for temperature-critical processes.
