High Frequency Epoxy for Electrical Modules, Flexible Circuits, Switches, Wave Guides, Flat Cable, Cold Solder Assembly & Repair 2919, 2919, 50 gm kit

- PRODUCT DESCRIPTION: AA-DUCT 2919 is a non-bleeding, electrically conductive, silver-filled epoxy formulation recommended for electronic bonding, coating, and sealing applications that require high flexibility coupled with good electrical and mechanical properties. This two-part, thixotropic adhesive of refined pure silver and epoxy resin components is free of solvents and copper or carbon additives. It develops resilient, electrically and thermally conducting bonds and coatings between many different and dissimilar materials such as metals, ceramics, glass and plastic insulates. AA-DUCT 2919 cures at room temperature and can be used as a flexible "cold-solder" for heat-sensitive components where hot-soldering is impractical. It also can be used for the assembly and repair of electrical modules, flexible circuits, membrane switches, wave guides, flat cable and high frequency shields. - PRODUCT DESCRIPTION: Appearance: Silver Cure Type: Room temperature or Heat cure Benefits: +Free of solvents and copper or carbon additives +Coatings between many different and dissimilar substrates +Mix Ratio by weight: 90:100 / Resin:Hardener +Substrates: Metal +Ceramics +Glass Thixotropic Index: 4.9 Typicall Application: Assembly and repair of electrical modules, flexible circuits, membrane switches, wave guides, flat cable and high frequency shields Electronic bonding, coating, and sealing applications Can be used as a flexible "cold-solder" - CURE SCHEDULE: 4 Hours: @ 65 °C 24 Hours: @ 25 °C - UNCURED PROPERTIES: Specific Gravity, mixed: 2.32 g/cc Pot Life: 30 mins Solid Content: 100% Volatile Organic Compounds (VOC) Content: 24.41 g Viscosity: 995000 cPs @ 25 °C - MISC PROPERTIES: Shelf Life: 1 Year Hardness, Shore D: 80 Adhesives Bond Strength: + Lap shear, alum to alum: 90 psi in 24hrs @ 25 °C + 170 psi in 4hrs @ 65 °C - ELECTRICAL PROPERTIES: Volume Resistivity: + 0.00011 ohm-cm cured 4 hrs @ 65 °C + 0.0016 ohm-cm cured 24hrs @ 25 °C - THERMAL PROPERTIES: CTE, linear: 19.4 µin/in-°F @ 68 °F Thermal Conductivity: 11.1 BTU-in/hr-ft²-°F Operating Temperature: -60.0 °C to 110 °C Glass Transition Temp, Tg: 4.00 °C, 39.2 °F - 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.
