CRC Clear Urethane Seal Coat Aerosol 300g

Urethane-based insulating coating for electrical applications

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

Due to chemical cross linking reactions ocurring after the drying stage, CRC Clear Urethane Seal Coat seals out water and moisture and is resistant to shock, abrasion, salt air and aggressive chemical atmospheres. The clear coloration allows for visual inspection and is ideal when a see-through coating is required. There is no mixing, no clean up, no excessive waste. It is easy to apply and saves time and labour.

Uses

• Insulating coating - Electric motor windings, armature coils, commutator ends, stator coils, terminals, housings, transformer ends, bus bars, solenoids, cables and wires, printed circuit boards
• Coating for components exposed to atmospheric effects - Terminal strips, screw connections, switch boxes
• Protecting components from condensation and moisture
