Encapsulate/Potting Compounds

Electrical Encapsulation

Polyurethanes are excellent for the encapsulation of electrical components and fragile wiring, due to the waterproofing and impact protection properties. These urethanes set up quickly and seal completely. 

Our encapsulation material performs well when continually submerged in fresh or saltwater. Keep your wires and electrical components protected from water and the environment with our polyurethanes.
