MasterSil 972TC-LO is capable of transferring heat with a thermal conductivity of 7-9 BTU•in/ft²•hr•°F [1.01-1.30 W/(m•K)], while retaining superior dielectric properties. It bonds well to a wide variety of substrates, including metals, composites, glass, ceramics as well as many types of rubbers and plastics. This addition cured system does not require air for cross-linking. It features low shrinkage upon curing even in thick or wide cross sections. MasterSil 972TC-LO has very good flexibility and high elongation. It can withstand aggressive thermal cycling as well as thermal and mechanical shock. This moderate viscosity system passes the rigorous requirements for low outgassing per ASTM E595 specifications. It is particularly well suited for use in vacuum environments as well as applications in the aerospace, electronic, opto-electronic and specialty OEM industries. MasterSil 972TC-LO is 100% solid and has a white color.
