Our production
Electrical insulation enamels, pastes, heat-conducting pastes
Electrical insulation enamels’ application is electric machines protection from the impact of low and high temperatures, moisture, acids, salts and other aggressive materials. Semi-conductive enamels are applied in high-voltage machines to ensuring electric field alignment and remove induced charge out of the insulation surface. Masctics are intended for surface leveling prior to application of tapes and enamel, slot wedges enforcement and spaces filling.
Electric insulation enamels:
Applied for creation of the protective and electric insulation coating. Enamel POLITERM 943 possesses heat resistance.
