Two Part Silicone That Meets NASA Low Outgassing Specifications

Master Bond has recently released its MasterSil 973S-LO, an adhesive, sealant and coating that passes NASA low outgassing tests.

Well suited for use in vacuum environments, the MasterSil 973S-LO features a low volume resistivity of 0.004 ohm-cm, and 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 to metals, composites, glass, ceramics, rubbers as well as many types of plastics. As is typical for most silicones, MasterSil 973S-LO 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 -120°F to +400°F [-84°C to +204°C].

MasterSil 973S-LO 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, it 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 250-300°F or 1-2 hours at 160-200°F.

MasterSil 973S-LO is available for purchase in 50 gram syringe kits. Additional sizes can be obtained upon request. It has a shelf life of 6 months at 75°F in its original, unopened containers.

This electrically conductive, two component silicone can be used in the aerospace, electronic, opto-electronic and specialty OEM industries.
