Adhesive, sealant and coating passes NASA low outgassing tests

Well suited for use in vacuum environments, Master Bond MasterSil 973S-LO is an adhesive, sealant and coating that passes NASA low outgassing tests. This electrically conductive, two component silicone can be used in the aerospace, electronic, opto-electronic and specialty OEM industries. Featuring a low volume resistivity of 0.004ohm-cm, the product is a silver filled compound that has a thermal conductivity of 9-11 BTU•in/ft²•hr•°F [1.30-1.59 W/(m•K)]. It bonds well to a wide variety of substrates, including metals, composites, glass, ceramics, rubbers as well as many types of plastics. As is typical for most silicones, It is highly flexible and has an elongation of 50-100%. This enables it to withstand thermal cycling and mechanical shock. Serviceability for this product is from -84C to +204C. It features a paste consistency with minimal flow, which allows it to be used as a formed-in-place conductive gasketing material. As an addition cured silicone, the compound does not require air for cross-linking. Unlike many silicones, it can cure wide cross sections and in depths beyond 1 inch. This formulation offers a variety of cure schedules at elevated temperatures, including 25-45 minutes at 160C-200C.
