A Perfect Pair: Dip Coating & the Electrical Industry

March 9, 2024

Metal is critical to the electrical industry primarily because of its excellent ability to conduct electricity. This same quality is what can also make it so dangerous when current comes in contact with people and objects that it shouldn't. With their very poor ability to conduct electricity, most plastics make excellent insulators — and make them the perfect partner for the electrical industry.

Why Plastic Coatings for the Electrical Industry?

Of course, we need to prevent electrical currents from passing unintentionally between parts in an electrical product or system, potentially causing damage, fire, or injury. Plastic coatings are commonly used to insulate everyone from linemen and electricians to homeowners and even their pets from physical contact with electricity. Not only do coatings protect people from electricity, they also protect vital electrical components from exposure to moisture, dust, debris, and other hazards.

Coatings for the Electrical Industry

While nearly any plastic coating can find applications in the electrical industry, some are more commonly used, including:


  • Plastisol (Vinyl)
  • Nylon
  • Epoxy
  • ECTFE (e.g., Halar)


These coatings can be applied in varying thicknesses, and offer excellent impact and abrasion resistance for electrical components, chemical, and moisture resistance. Many coatings are suitable for high-voltage applications such as bus bars, bus bar boots, underground tap connectors, power distribution connectors, and the tools used to work in high voltage environments.

Coatings for Household Electrical Systems

Residential wiring is coated in plastics such as vinyl, nylon, ECTFE (Halar), and polyethylene. These plastics are flexible, durable, and are excellent insulators, making them suitable for the cramped spaces and many angles required in household wiring. By applying such coatings, we can help prevent sparking, arcing, and other hazards which can cause fires, damage, injury, and system failures.
