Atmospheric pressure plasma technology improves the surface energy by adding in extreme surface (a few nanometers) a large quantity of polar chemical functions. These polar functions generate numerous Van Der Waals interactions with the activated material, to improve its wettability and increase the adhesion of the coating.
The atmospheric pressure plasma implemented is blown; thus it allows to add in extreme surface chemical functions that are electrically neutral, which avoids any ESD phenomenon.
This plasma technology also allows fast selective treatment, consistent with the shortest cycle times and selected coating zones.
