Features of MasterSil 973S-LO


  • A silver filled compound that has a thermal conductivity of 9-11 BTU•in/ft²•hr•°F [1.30-1.59 W/(m•K)]
  • A low volume resistivity of 0.004 ohm-cm
  • It bonds well to a wide variety of substrates, including metals, composites, glass, ceramics, rubbers as well as many types of plastics
  • The Product 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].

Applications


  • 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, MasterSil 973S-LO 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.
