Corona Surface Treatment System
Summary:
Softal’s corona treatment system is composed of a high-efficiency generator and a durable, compact treatment station. The system improves the adhesion of printing ink, adhesives, lacquer, and various coatings to a wide range of substrate surfaces.

Characteristics:
Generator
High-efficiency, stable output based on resonance circuit technology
Simple operation via a touch panel
Rapid normal return via a self-diagnostic function
Interface function with the production line
Output is possible over a wide range from 1 kW to 60 kW

Treatment Station
High-efficiency discharge via a specially designed electrode
Realizes space reduction via a compact design
High-efficiency ozone exhaust
Simple calibration and operational functions
High stability via a fine interlock function
Wide range of models for treatment widths of 200 mm to 10 m

Outline:
Softal’s “Aldyne” atmospheric linear plasma surface treatment system generates plasma discharge in a mixed gas atmosphere having a base of nitrogen gas to bond the added gas molecules to the substrate surface. As such, high polarity, functional amide and amino groups are generated.
In addition, using the nature of these groups to readily form covalent bonds with the functional groups in the coating, it is possible to increase the strength of bonding between the substrate and coating.

Characteristics:
Achieves a high adhesion unobtainable with corona treatment
Adhesion is long-term with no change over time
