Technical Product Bulletin
ELECTRICALLY CONDUCTIVE ONE PART LOW COST EPOXY
PRODUCT DESCRIPTION
AA-DUCT AD1 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 AD1 shows slight settling when stored for a long period of time, no caking and will re-disperse to a smooth homogeneous state.
AA-DUCT AD1 formulation produces electrically conductive paths on a wide variety of surfaces including plastics, rubber, cloth, thermoplastic, paper, wood and many others.
AA-DUCT AD1 designed for use in diversified applications 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.

GENERAL INFORMATION
For safe handling information on this product, consult the Material Safety Data Sheet, (MSDS).
HOW TO USE
- Carefully clean and dry all surfaces to be bonded.
- Apply AA-DUCT AD1 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.
- 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.
- 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.
AVAILABILITY
This epoxy can be supplied in various different packages.
