Two-part silicone system meets NASA low outgassing specifications
Master Bond MasterSil 972TC-LO passes the requirements for low outgassing to ASTM E595 specifications and 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 a two part silicone system offers convenient handling for bonding, sealing, coating and potting and is an electrical insulator that has excellent thermal conductivity. 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.
It does not require air for cross-linking and 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 50g syringe kits with additional sizes upon request.
