8331
Technical Data Sheet
Silver Conductive Epoxy Adhesive
Description
8331 is an electrically conductive, silver-lfiled two-part epoxy adhesive. It is smooth, non-sagging,
thixotropic, and bonds well to a wide variety of substrates.
This product allows for quick, cold-soldering repairs. It can also be used as a solder replacement for
bonding heat-sensitive electronic components, or for making conductive connections where soldering is
not an option, such as when bonding to glass, soft metals, or plastics.
8331 has been formulated to be economical. For a higher fill that maximizes conductivity, use 8330. For
a longer working life, use 8331S.
