Technical Data Sheet
Silver Conductive Epoxy Adhesive
Description
8330 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.
8330 is highly filled to maximize electrical conductivity. For a more economical version, use 8331.
For a longer working life, use 8330S.
