MasterSil 972TC-LO is capable of transferring heat 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 rubber and plastics. The system has very good flexibility and elongation. It can withstand aggressive thermal cycling as well as thermal and mechanical shock. The system is 100% solid and has a white color.
Master Bond MasterSil 972TC-LO 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. This two part silicone system
offers convenient handling for bonding, sealing, coating and potting.
MasterSil 972TC-LO is an electrically insulator that has a thermal conductivity of 7-9 BTU•in/ft²•hr•°F [1.01-1.30 W/(m•K)]. It bonds well to a wide variety of substrates, including metals, composites, glass, ceramics, rubbers as well as many types of and plastics. Highly flexible, MasterSil 972TC-LO has an elongation of 40-80%, withstands aggressive thermal cycling and resists mechanical shock. This heat dissipative silicone system has a wide service temperature range is -120°F to +400°F.
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 a moderate viscosity of 30,000-40,000 cps with good flow properties and has a one to one mix ratio by weight. It has a long working life of 6-10 hours at room temperature. This compound is 100% solids and has a white color. Mastersil 972TC-LO is available in 50 gram syringe kits with additional sizes upon request.
