Appli-Thane® 7330

2.5 W/mK - A two-part flowable urethane with excellent thermal conductivity

Appli-Thane® 7330 is a two-part thermally conductive polyurethane adhesive. As it meets NASA’s outgassing requirements, it’s ideal for electrical potting and aerospace applications. The cured material will not crack or harm bonded rigid components during thermal cycling.
