Transformers Function Better with Polyurethane and Epoxy Potting and Varnishing Compounds

Transformers are exposed to hot temperatures and high voltage. To function properly, they need component protection. Epic Resins manufactures thermally conductive polyurethane potting compounds providing insulation for transformers. With capabilities suited for parts in dangerous conditions, our polyurethane and epoxy compounds prove their worth with superior results.

Benefits of Epoxy Resin for Transformer Applications

Built for telecommunications industries, Epic Resins’ polyurethane and epoxy potting compounds are formulated to resist heat and water, and to deter rusting and eventual system breakdown of PCB components.
