Technical Product Bulletin

ELECTRICALLY CONDUCTIVE ADHESIVE FLEXIBLE SILVER EPOXY NON BLEEDING


PRODUCT DESCRIPTION:

AA-DUCT 917 is a non-bleeding, electrically conductive, silver-filled epoxy formulation recommended for electronic bonding, coating, and sealing applications that require 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 917 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.

GENERAL INFORMATION:

For safe handling information on this product, consult the Material Safety Data Sheet, (MSDS).

HOW TO USE:

1) Carefully clean and dry all surfaces to be bonded.

2) Apply AA-DUCT 917 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.

AVAILABILITY:

This epoxy can be supplied in various different packages.

Data Sheets: TDS | MSDS available upon request.
