CRC/Barcode Name Pack Size
Aerosol 300 g 6

CRC Red 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 occurring after the drying stage, CRC Red Urethane Seal Coat seals out water and moisture and is resistant to shock, abrasion, salt air and aggressive chemical atmospheres.

A special iron oxide pigmentation system yields additional film resistance without sacrificing electrical values.

The red coloration allows for easy visualisation and proof of application build.

There is no mixing, no clean up, no excessive waste. It is easy to apply and saves time and labour.
