SolEpoxy coating powders provide electrical insulation and environmental protection in a broad array of applications including motor iron, bus bars, toroid cores and passive devices such as capacitors and resistors.

Our epoxy powders are manufactured to strict quality standards for environmental, health, and safety compliance. Plus, they are easy to use. Powder coatings minimize VOCs and enable precise and uniform surface coverage.

Unique Characteristics

SolEpoxy innovates new products to meet changing market demands, as well as creating custom formulations to meet your needs. We also supply engineered particle sizes including extra fine grinds to top-up and restore the optimum particle size distribution in fluidized bed processes. Our powder coating products are characterized by:

  • Outstanding chemical resistance, including motor oil, fuel, etc.
  • 100% solids content (VOC-free)
  • Low coating thickness required to achieve maximum performance
  • High coating thickness (100+ mil) to achieve medium voltage protection
  • Excellent cut-through resistance
  • Excellent edge coverage
  • High service temperatures
  • Capability to provide a range of thermal conductivity
  • Both induction cure and oven cure chemistries
  • Reduced cost vs. traditional slot liners
