What Is Dielectric Coating?

In short, dielectric coatings are insulators, blocking the flow of electric current beyond the highly-conductive metal they cover. This works because of the differing molecular structure of good conductors, such as metal, and poor conductors, such as plastic and wood. Dielectric coatings bring additional benefits, including resistance to environmental hazards and exposures, and protection against wear and abrasion, all of which can compromise electrical parts and increase the risk of shocks. These coatings offer improved safety for numerous applications, including:

• High-voltage tools and parts
• Power distribution components
• PPE and other safety equipment

Which Coatings Offer the Best Dielectric Protection?

Dielectric coatings can be applied by dipping, or by electrostatic spray or fluidized bed techniques, depending on the material selection, coat thickness needed, and the part being coated. Popular dielectric coatings include:

• Epoxy — Epoxy coating is extremely hard and durable, and offers excellent protection on even sharp edges which can challenge other coatings.
• Halar — This fluoropolymer coating is exceptionally smooth (minimal friction) and resilient, commonly used for coating microelectronics components.
• Nylon — Durable, sterile, and renewable, nylon offers long-lasting protection
• Plastisol — This vinyl-based coating is a go-to solution for high-voltage tools and components, protecting linemen and others in direct contact with live electrical currents.
• Vinyl — Effective, durable, and economical, vinyl coatings offer excellent protection against most chemical and environmental exposures while providing solid insulation against electrical current.
