Transformers Function Better with Polyurethane and Epoxy Potting and Varnishing Compounds

Transformers suffer through a lot of wear and tear, exposed to hot temperatures and high voltage. In doing its job properly, such devices require component protection. Epic Resins manufactures thermally conductive polyurethane potting compounds providing superior encapsulation 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 industries in telecommunications, Epic Resins’ polyurethane potting compounds perform to the benefit of the protected components. Our epoxy and polyurethanes can be formulated to resist heat and water, deter rusting, degradation, and eventual system breakdown of PCB components and more.

Other featured benefits of our potting compounds include:

  • Thermal shock-resistance
  • Adhesion
  • Strength and Durability
  • Electrical Insulation
  • Thermal Conductivity

Other Industries with the Epic Resin Advantage

Besides telecommunication, other industries and their offshoots reap in the benefits of our polyurethane potting compounds. Businesses in need of reliable encapsulating, insulating, and adhesive material depend on our quality line of epoxy and polyurethane resin manufacturing services—and we render top-of-the-line products every day. 

Applications benefitting from our quality-crafted resins include:

Pool/Spa Filters- our resins resist water leakage and cleaning chemicals, letting filters do their job without breakdown

Wind Energy- adhesively strong and heat-resistant, our epoxies and polyurethanes are perfect for continuous movement and withstanding harsh weather

Automotive- our products protect ignition coils and electrical components from moisture and heating up other fragile surrounding parts

Solar Energy- epoxies and polyurethanes from Epic Resins withstand all damaging weather environments with its strong adhesive properties
