8820 - High Temperature Rigid Urethane
8820 is a black, tough, high temperature, two-part polyurethane potting compound. It has a low mixed viscosity and properties similar to epoxy compounds, but with exceptional low temperature stability. As well, it adheres strongly to a wide variety of substrates, including metals, composites, glass, ceramics, and many plastics.
8820 offers exceptional physical protection, a high continuous operating temperature, and superior protection from acids, bases, and many organic solvents.
