Master Bond Releases Supreme 121AOND Toughened Epoxy
Master Bond's Supreme 121AOND toughened, non-drip epoxy is a two-component, heat-curing system with a thixotropic paste consistency.
Is said to provide excellent chemical resistance while also offering a high glass transition temperature (Tg) of 200-210°C. Meets NASA low outgassing specifications per ASTM E595 testing and has reliable electrical insulation properties with a volume resistivity exceeding 1014ohm-cm at 75°F. Possesses high bond strength with a tensile strength of 6,000-7,000psi and a tensile modulus of 750,000-850,000psi at room temperature, with a tensile modulus of 650,000-750,000 psi at 300°F. Features thermal conductivity of 4-5 BTU•in/(ft²•hr•°F) [0.58-0.72 W/(m•K)] and offers a wide service temperature range from -80°F to +550°F (-62°C to 288°C). Is said to bond well to a wide variety of substrates including glass, fibers, metal, ceramics, rubbers and plastics.
