Common sprayed insulation layers, for example made of Al₂O₃, ZrO₂ or Cr₂O₃, are microporous and often
hygroscopic. This means they can absorb moisture, which can impair the electrical insulation effect. A suitable sealer in accordance
with DIN EN ISO 14924 can help and can even improve the insulation properties.
We offer highly effective sealants with tested proof of function for the electrical insulation of thermally sprayed coatings.
As part of a product development project, we have developed a sealant with electrical insulation properties for our customer Plasmatic Franken GmbH. In combination with the spray coating, the sealant provides electrical insulation of 10 GW at a voltage (DC) of 1,000V. Following successful pre-series production, Plasmatic is now using the sealant for hundreds of components in series production. Are you also looking for a reliable solution for the electrical insulation of your spray coating?
Rolling bearings for electric motors, such as those used in rail vehicles, are exposed not only to mechanical but also electrical loads. Special ceramic insulating coatings are used to prevent damage in the form of electrical erosion caused by high-frequency currents. sealer of these spray coatings plays a central role. The sealer increases the electrical insulation of the coating and reduces friction in the drive train. This increases the service life of the rolling bearing and enables a reduction in energy and material during production. This not only makes the rolling bearings more economical, but also more sustainable.
