    Urethane Potting Compounds

    Encase electronic assemblies in a layer of urethane for protection from dust, moisture, chemicals, mechanical shock, and vibration. Urethanes withstand a wide range of temperatures and are the best choice for cold-temperature applications. They have excellent flexibility, good chemical and moisture resistance, and provide good electrical insulation.
