Master Bond (Hackensack, NJ) now offers the Supreme 121AO, a NASA low outgassing approved epoxy suitable for bonding, sealing and potting applications. Featuring a high glass transition temperature of 200-210°C, it resists temperatures up to 550°F. This system exhibits an element of toughness, and is not as stiff as conventional epoxies that withstand extreme temperatures. Features include:
- A noteworthy strength profile with a tensile modulus of 750,000 to 850,000 psi at room temperature and a compressive strength of 26,000 to 28,000 psi.
- Thermal conductivity of 4-5 BTU•in/(ft2•hr•°F); it is also electrically non-conductive. Shrinkage upon cure is exceptionally low.
- The ability to withstand thermal cycling and mechanical stresses. It also resists many chemicals, including water, oils, fuels, acids and bases. Supreme 121AO may be used in aerospace, electronic, opto-electronic and OEM applications.
