8331 is an electrically conductive, silver-filled 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.
