In numerous customer studies, the effects of different physical pretreatment methods such as corona and plasma pretreatment as well as chemical fluorizing were investigated in depth and compared with one another. Critical assessment criteria were the level of activation achieved on the profiles, the adhesion values, and the durability of the pretreatment.
The results speak clearly in favor of plasma pretreatment. The Openair® Plasma process proved to offer excellent long-term stability, similar to that of fluorizing. EPDM profiles pretreated using the corona method showed a significant drop in surface tension only a short while after treatment.
Compared with fluorizing, pretreatment with Openair® Plasma as a purely physical process delivers major processing and cost advantages. Moreover, the plasma technique is very much kinder to the environment as it requires no chemicals whatsoever.
