Urethane potting and encapsulating compounds offer advantages when needing to cure at lower temperatures and/or quickly compared to epoxy systems. Urethanes offer better flexibility and crack resistance as well as better adhesion to certain substrates such as many plastics and composites. Many urethane products Epoxyset offers use renewable raw materials making it less harmful to the end user. It is ideal for electronic applications, surface mount technology, and when thermal cycling resistance is a requirement. Epoxyset urethane potting materials have low CTE rates ensuring flexibility at even extremely low temperatures.
