Atom Adhesives AA-DUCT 904 Epoxy Adhesive
Categories: Polymer; Adhesive; Thermoset; Epoxy; Epoxy Adhesive

Material Notes: 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.
