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.
FEATURES:
- 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.
