With the absence of strong electrostatic field, the charged particles are able to penetrate into the deep recesses of complicated-shaped objects, overcoming the ‘Faraday Cage’ effect.
This system also produces a more even coating with superior finishes – less pin-holes and craters due to the ‘back-ionisation’ effect.
The main set-back of this method of application is the poorer charging capacities of each gun compared to the conventional electrostatic gun – i.e. more tribo guns are needed for the same through-put of total area coated.
The charging ability also depends on the type of resin system used.
