UV rays and active oxygen particles in the plasma break various bonds and remove silicone and oil from the surface. Active oxygen radicals bind to the entire surface, which becomes highly active for new bonds.

The plasma activation test
The effect can be measured with the following test options.
Contact angle measurements
Water droplets on an untreated surface retain the shape of a drop. On a treated surface, the drop spreads over the surface.
Dyne test inks
Dyne test inks give an indication of the surface energy or surface tension in mN/m (set from 28 mN/m to 105 mN/m).
