La energía superficial es un parámetro muy importante para los sustratos que deben tratarse en procesos como el pegado, el barnizado o la impresión.
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.
