Processes: Smooth processes and defined surfaces for the painting process

A perfectly pretreated surface is a precondition for the subsequent painting process.

Environmentally friendly water-based painting processes – made possible by pretreatment of material with atmospheric-pressure plasma - are a central part of production in many companies. 

Openair® plasma technology renders the surfaces of materials free of grease and free of dust and at the same time provides them with higher surface energy. Due to the cleaning effect of pretreatment with plasma degreasing occurs, the antistatic action of the plasma removes adhering particles of dust and the chemically reactive effect increases surface energy. This combination makes Openair® plasma a highly effective tool. Additional washing and priming processes can generally be dispensed with.

Openair® plasma ensures the adhesion of paint

In this pretreatment process the plasma jets are frequently directed by robot systems. Ideal fields of application of atmospheric-pressure plasma include, for example, the automotive and aviation industries, the production of household appliances and the packaging industry. Plasma ensures the adhesion of surface coatings to metals, aluminium and plastics, such as PP and EPDM, and to numerous other materials.
