Electrical Potting Compounds for Coil Assemblies and Automotive Parts

Coil Potting Compounds for Exceptional Insulation

Epic Resins has a complete line of epoxy resin polyurethane electrical potting and encapsulating compounds designed to have superior electrical insulating properties for coils. When potting electronics, superior resistance to environmental factors is as critical as exceptional insulation of electronic components. On both counts, Epic Resins leads the industry.

Along with decades of experience developing specialty epoxy and polyurethane resins, Epic Resins brings a customer-centric focus to all our work. Our expertise and extensive inventory of epoxy resins provide clients the opportunity to get cost-effective custom formulations for their specific needs. Our potting material offers supreme resistance to chemicals, wear, moisture and other hazards, while our encapsulants come in a wide range of viscosities specially designed for difficult to impregnate coil assemblies.

Below are just a few examples of our electrical potting compounds currently being used by the automotive industry to protect ignition coils and ensure smooth engine start-ups.
