High strength Silver Epoxy, Electrically Conductive for microwave, EMI & FRI shielding assembly & PCB, electronic component manufacturing & Repair 904, 250gm Jar

- PRODUCT DESCRIPTION: AA-DUCT 904 is a single component, heat curing, conductive epoxy that was designed for ease in handling. This high performance conductive epoxy cures quickly at elevated temperatures making it ideally suited for rapid processing and assembly. AA-DUCT 904 offers excellent mechanical, electrical, and physical properties at continuous operating temperatures up to 175°C. This versatile silver conductive adhesive can be used for chip bonding in micro and opto-electronic hybrid circuit fabrication. AA-DUCT 904 has also been used in microwave applications for EMI and FRI shielding, for assembly and repair of circuit boards and electronic component manufacturing. AA-DUCT 904 is a smooth, soft paste that can be applied by hand application, automatic dispensers, screen-printing, transfer or stamping techniques. It is available in both a lower and higher viscosity grade for use in a variety of dispensing equipment and application techniques. - CURED PROPERTIES: Hardness, Shore D 83 - PRODUCT PROPERTIES: Appearance Silver Cure Type Heat cure Benefits: + High strength + Excellent mechanical, electrical properties Substrates: Excellent choice for Integrated Circuits, aluminum, copper, magnesium, steel, bronze, nickel, ceramic, glass, phenolic and G-10 epoxy glass boards. - CURE SCHEDULE: 2 hours @ 125°C 1 hour @ 150°C 1/2 hours @ 175°C - UNCURED PROPERTIES: Viscosity @ 25 °C cps: 200,000 Shelf life: 6 Months Density: 3.6 - THERMAL PROPERTIES: Thermal Conductivity, btu/hr/ft2/°F/in 16.1 Coefficient of Thermal Expansion 60x 10^-6 (in/in) C Operating Temperature: + -55°C to +175°C + Intermit. to 325 - ELECTRICAL PROPERTIES: Volume Resistivity ohm. cm 0.001 - NASA OUTGASSING RESULTS: TML (Total Mass Loss) % 0.38 CVCM (Collected Volatile Condensable Materials) % 0.01 WVR (Water Vapor Recovery) % 0.07 - GENERAL INFORMATION: For safe handling information on this product, consult the Material Safety Data Sheet, (MSDS). - AVAILABILITY: This epoxy can be supplied in various different packages.
