  • Such powder coating processes are particularly popular for high throughput speeds of the coating substrate applied up to 3 m / s. applications this is, for example, the powder coating of insulation boards that supported electrostatically Applying abrasive grain to paper and Plastic film, the solder powder application on Extruded materials, the clear powder coating of wallpaper and powdering equipment e.g. For electrical cables or in the food sector.
  • the detachment of the powder particles is additionally supported in which the Powder particles in the transmission area are electrically charged can be and so the particles differ from the transfer band due to the electrostatic It is easier to detach the repulsive force from its surface can. This also causes agglomeration of the Avoided particles. Just through the powder charge is a transfer of the particles to the substrate not possible.

This is particularly easy possible with substrates with a uniform surface geometry. Because of the reproducible controllable Amount of on the transfer device and last on the powder transferred to the substrate are also very low Powder quantities per unit of time in contrast to State of the art transferable. So that are thin-layer applications reproducible down to a few ⁇ m thickness possible. The thickness of the layer is determined thereby essentially from the speed of the Transfer device, the speed and the relative Direction of movement of the substrate as well the amount of applied to the transfer device Powder.
  • the powder material transferred to the substrate without losses i.e. elaborate technical measures for recovery and recycling the not on the substrate deposited powder, as in the previous electrostatic powder application using spray organs are required. This is with less Space requirements and lower investment costs connected.
