Epoxy Insulating Coating Powders

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.

Strengths: Arc Resistance, Dielectric Strength, Surface Appearance, Edge Coverage, Temperature Rating, & "Green" Flame Retardants

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

Methods of Application

SolEpoxy's line of coating powders for the insulation and protection of electronic and electrical devices is designed to be applied in the full range of powder application equipment, including:

  • Standard fluid bed machines for coating both electronic and electrical devices including the small manual machines or the very large fully automated types. These powders provide very level bed surfaces with little or no dusting.
  • Cascade coating machines for axial leaded electronic devices. SolEpoxy's powders transport well to the application areas and coat with very little dusting.
  • Standard epoxy spray coating equipment for the integral insulation of motor armatures and stators in which the powder is blown onto the preheated part. Our powders are formulated to provide high edge coverage and good cut-through performance. Grades are available which do not require post curing.
  • Electrostatic fluid bed equipment for the coating of electronic devices and of electrical motor stators and armatures. SolEpoxy's powders are designed to provide the maximum charge acceptability. The particle size distribution is carefully controlled. These two factors allow for good control of film thickness.
  • Inline wheel coating equipment for radial leaded components. SolEpoxy's powders are designed to be compatible with this type of coating application.
