Electrolube aromatic-free polyurethane conformal coating

The aromatic-free polyurethane conformal coating (PUCAF), from Electrolube, has been specifically designed for the protection of electronic circuitry. The coating utilises a specialist blend of solvents ensuring the product is completely free from aromatic content, while offering ease of use via all types of application method, including manual and selective spray processes.

The modified polyurethane conformal coating is tough, flexible and increases throughput due to a rapid touch dry time of less than 10 min. Certified and compliant with REACH, RoHS, UL94 V-0 and IPC-CC-830, PUCAF fluoresces under UV light to aid inspection and provides good mechanical and dielectric properties.

The aromatic-free coating demonstrates adhesion to many substrates, has a wide operating temperature range and is highly resistant to mould growth and moisture. Once cured, the coating can also be removed with the conformal coating remover gel (CCRG), a thixotropic gel that excludes the use of dichloromethane.
