Glow Discharge Device

Substrate pre-treatment with the VON ARDENNE glow discharge device is the ideal solution for the cleaning of temperature sensitive, non-conductive materials and surfaces. The substrate is cleaned by a low-pressure plasma discharge in a very gentle way as only mildly adhesive loose atoms and molecules are removed.

Therefore, glow discharge devices are especially suited for removing adsorbed water films on substrates like polymer films, glass and metal with isolating surface layers (e.g. lacquered surfaces or anodized aluminum layers).

A distinct advantage of glow discharge is that only little heat is generated. Therefore, this method protects the substrates and adds only a little heat input to the subsequent coating processes.
