MG Chemicals 4223F-1L Liquid 

The 4223F Polyurethane Conformal Coating is a heat curing, one part product that provides an excellent scratch, chemical resistant finish, meets UL 94-V0, and free of xylene and other hazardous air pollutants. This one part coating is easy to use and repair: it does not require special or costly equipment or materials. It is ideal for chemically challenging environments.

The 4223F urethane protects electric circuits against aggressive chemicals, moisture, dirt, dust, thermal shocks, and scratches. This avoids corrosion and physical damages to electric components. It insulates against high-voltage arcing, shorts, and static discharges, allowing for traces to be put closer to one another.
