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. Use a gun (sold separately) with the included mixer nozzle to dispense.
US2350™ also require a 4:1 plunger (sold separately) to dispense.
