Master Bond (Hackensack, NJ) MasterSil 323AO-LO is a two component silicone elastomer with a self-priming feature, designed for bonding, sealing and gap filling applications. This electrically insulating and thermally conductive compound meets NASA low outgassing specifications and can be used in the aerospace, electronic, opto-electronic and specialty OEM industries. Specifically:
- This system has a thermal conductivity of 1.15-1.30 W/(m•K).
- It is highly flexible with a low tensile modulus of 500-700 psi, an elongation of 50-60%, and a hardness of 70-75 Shore A. This combination of properties enables it to withstand aggressive thermal cycling and mechanical shock.
- MasterSil 323AO-LO has a relatively high strength profile for a silicone with a tensile lap shear strength of 250-350 psi at room temperature.
- It bonds well to a wide variety of substrates, including metals, composites, glass, ceramics, plastics and other silicones without imparting residual stress when heat cured. Serviceability is from -65°F to +400°F [-54°C to +204°C].
