AA-DUCT 905 is a single component epoxy, formulated with pure silver powder combined with organic binders and solvents to produce electrically conductive paths, films or patterns over non-conductive substrates.
AA-DUCT 905 shows slight settling when stored for a long period of time, no caking and will re disperse to a smooth homogeneous state.
AA-DUCT 905 formulation produces electrically conductive paths on a wide variety of surfaces including plastics, rubber, cloth, thermoplastic, paper, wood and many others.
AA-DUCT 905 is designed for use in diversified applications such as microwave EMI & RFI shielding, in the assembly or repair of printed circuit boards, wave-guides, electronic modules, flat cable, static shielding, connections and circuitry. This epoxy is designed for screening and micro product adhesion applications with the best dispensing capabilities of up to 30 gauge / 0.01"/ 0.255mm.

HOW TO USE:
1) Carefully clean and dry all surfaces to be bonded.
2) Apply AA-DUCT 905 completely mixed adhesive to the prepared surfaces, and gently press these surfaces together. Contact pressure is adequate for strong, reliable bonds; however, maintain contact until adhesive is completely cured.
3) Some separation of components is common during shipping and storage. For this reason, it is recommended that the contents of the shipping container be thoroughly mixed prior to use.
4) Some ingredients in this formulation provided may crystallize when subjected to low temperature storage. A gentle warming cycle of 52°C for 30 minutes prior to mixing components may be necessary. Crystallized epoxy components do not react as well as liquid components and should be re-dissolved prior to use for best results.
