CRC Urethane Seal Coats
Electrical - Electronic Coating Insulator
CRC Urethane Seal Coat is a single component polyurethane coating that offers excellent adhesion. It is commonly used to re-insulate after repairs to electrical or electronic circuitry and electric motor rewinding.
Ideal For:
Protective coating for printed circuit boards.
Coating for: Electric motor windings, armature coils, boxes, controls, commutator ends, terminals, housings, transformer connectors, bus bars, solenoids, tools.
Features
- High di-electric strength
- Flexible and non-conductive film
- Dries fast
- Available in two colours - red or clear
- Red yields additional film resistance without sacrificing electrical values. It is most commonly used in all electrical motor rewinding.
Approvals
- USDA Authorised for use in Federally inspected Meat and Poultry Plants.
- NSN 5970-01-017-5738 RED
NSN 5970-01-101-7019 CLEAR
