Urethane Potting Materials

ResinLab offers a series of urethane encapsulants which are much softer than epoxies. They can cure in a wide variety of gel times with much lower exotherm and stress than epoxy.

Our urethanes also offer much better performance in low temperature (-40C) applications as they maintain a high degree of flexibility. Additionally, our urethanes perform better than epoxies when subjected to thermal cycling and offer much better adhesion to plastics.
