Impregnating Resins and Varnishes - Electrowind | Products for ...

Impregnation Resins and Varnishes 3Vacuum Pressure Impregnation (VPI) ResinsVacuum pressure impregnation is a leading process for the handling of resin in tractionmotors, high-voltage motors and generators. Whether your company uses a single-baror a global impregnation process, we assist you in selecting the most appropriate resinfor your application, equipment and expected performance.Thanks to our expertise in VPI systems, system components and high-voltage testing,we are able to provide unrivalled guidance in testing and assessing the performance ofour resin in your system.Finally, once you have selected the resin that best fits your needs, please ask for ourtechnical support for the first impregnation trials: we will help you to fine-tune yourprocesses to get the most out of our impregnation resin.This selector guide includes a selection of our finest resin choices in either epoxy,polyester, polyesterimide or silicone chemistries. All these resins have been tested andproven in our own laboratories and have been successfully used by our customers.1.Transfer preheatedobject to vacuum vessel.Pull vacuum.2.Transfer resin under vacuum(the vacuum pump must beclosed). Allow time to soak.3.Release vacuum.Apply positive pressure.4.Transfer resin back to storagetank.
