Clear Urethane - Electrical / Electronic Insulator

CRC Clear Urethane is a stable single component polyurethane coating for electrical and electronicapplications. It dries fast, adheres well and forms a hard, durable, flexible and non conductive film for electrical motor windings and armature coils

CRC Urethane Seal Coats are an excellent adhering one-component polyurethane coatings. Its abrasive resistant insulation acts as a protective film, for electrical and electronic applications. CRC Urethane Seal Coats are stable single component polyurethane coating that dries fast, adheres well and forms a hard, durable, flexible and non-conductive film.

Applications: Recommended for:

  • Protecting components from condensation and moisture
  • Protecting printed circuit boards.
  • Insulates cables and wires
  • Coating terminal strips, screw connections, and switch boxes that are exposed to atmospheric effects.
  • Coating for Electric motor windings, armature coils, commutator ends, transformer ends.
  • Coating for housings and bus bars.
  • Protective coating for tools.


  • Clear or Red. Available in two conformal colours.
  • Humidity and Salt Spray Resistant. Provides heavy corrosion protection to preserve and lengthen useful life of equipment.
  • Protection. Offers protective resistance to shocks, abrasion and aggressive chemicals atmospheres.
  • High Dielectric Strength, and a high surface and volume resistivity which, when combined with a low dielectric constant and dissipation factor, are necessary for
    successful electrical and electronic applications.
