Conveniently packaged, and easy to use, these compounds exhibit outstanding performance properties in service. They are designed to withstand prolonged exposure to elevated temperatures, thermal cycling and vibration and shock. Particularly noteworthy is their exceptional thermal dissipation properties. These formulations are available in one and two component systems. They consist of epoxies, silicones, polyurethanes and elastomeric contact cements. Grades that cure at room temperature and upon exposure to heat can be purchased for use. Special grades meet NASA low outgassing specifications.
