Corona discharge generator for surface treatment
SpotTEC
Tantec
The pre-treatment of plastics before coating, bonding or printingis aimed at improving adhesion. Pre-treatment is often required so that enhanced wettability and optimum adhesion of the coating are achieved.
The SpotTEC Corona Generator offered by Tantec permits
simple pre-treatment of surfaces for three-dimensional moulded or
extruded plastic parts, profiles, etc. with low investment and running
costs.
The SpotTEC is based on the principle of high-voltage discharge in the highfrequency area. A blower presses the discharge, which is established
between the two electrodes integrated in the discharge head, against the
substrate to be treated, thus obviating the need for a counter electrode.
The SpotTEC can be integrated easily and quickly in new or existing production lines. The system is available with a single or double electrode head; other versions are available on request.
The SpotTEC complies with the CE requirements and EMC regulation.
Advantages:
· Monitored discharge with timer and alarm functions
· Flexible treating depth
· Simple handling
· Processing speed up to approx. 20m/min
· Multi-head solutions possible without major investment
