Melting possibility of powder coatings using HF energy was studied. The research was implemented in 3 phases. We concentrated on examination of dielectric characteristics of the powder coating, additives and MDF (medium density fibre board) first. The measurments were executed with the help of the AGILENT 4285A PRECISION LCR METER device. Then we tried to melt the powder coating, applied on MDF, at different parameters of HF generator, in a condensator specially adapted for this purpose. The properties of the achieved cured film were checked last. We found out that the HF energy would be appropriate for hardening of the power coatings. To apply this technology into the production successfully the new type of the power coating with a higher dielectric value should be developed.
