Epic Resins Polymers for Industry Since 1958

Epoxy & Polyurethane Potting Compounds for Battery Packs

The perfect battery pack potting or encapsulating compound depends on your application’s needs. Our team of chemists partner with you to recommend products or develop solutions fit for your specifications. We offer battery pack epoxy resins and polyurethanes for:

  • General Industrial Applications
  • Power Tools
  • E-Mobility Batteries

Electrical vehicle batteries face unique challenges: managing thermal conductivity, mitigating thermal runaway propagation, and performing in extreme temperatures (high and low).

We offer a line of Underwriters Laboratory (UL) recognized products, safe for elevated temperature environments. Your battery pack is better able to withstand the stresses of high operating temperatures with our high-quality potting and encapsulating compounds.

Popular Battery Pack Potting and Encapsulating Compounds:

  • Epic S7593 is a two-component polyurethane encapsulant that is thermally conductive and self-leveling. S7593 is designed to have a high thermal conductivity, 94-V0 at 1/2" and long pot life for ease of manufacturing. S7593 will require a unique process and mixing equipment for use.

  • Epic S7527 is a two-component polyurethane potting compound formulated for applications requiring thermal stability at high temperatures. S7527 carries a UL 94V-0 flame rating and a 150°C RTI rating per UL 746. Epic S7527 is excellent for potting and encapsulating sensitive electronics that are exposed to harsh environments.
  • Epic S7475 is a two-component polyurethane compound for potting electronic control modules and a wide variety of electronic devices. Low mixed viscosity allows the material to flow into intricate areas under printed circuit boards and other tight-tolerance areas. A 4:1 mix ratio allows the system to be very adaptable for meter mix and dispense processing. The very low hardness of S7475 in combination with the low Tg provides excellent flexibility, allowing delicate surface-mounted devices to expand and contract during thermal cycling and thermal shock. For applications that generate high heat, S7475 has shown extremely low weight loss at 130°C. It is UL 94 V-0 recognized at 4.8 mm and is RoHS compliant.

 

  • Epic S7242 is a two-component epoxy potting and casting compound. This product features a low coefficient of thermal expansion, can be hand or meter-mix dispensed, and is non-abrasive.
  • Epic RM17A5302 is a two-component polyurethane potting compound designed as a soft thixotropic material for holding large electrical components in place. RM17A5302 is formulated with a convenient 2:1 by volume mix ratio and fast cure.
