CRC/Barcode Name Pack Size
Aerosol 300 g 6

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.
