8331D is an electrically conductive, 2-part silver epoxy adhesive. It is smooth, non-sagging, thixotropic, and bonds well to a wide variety of substrates.This electrically conductive silver epoxy allows for quick, cold-soldering repairs. It is considered a solder replacement epoxy 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. It provides excellent EMI/RFI shielding and is very effective in filling seams between metal plates.This DIY conductive epoxy has been formulated to be economical. For a higher fill that maximizes conductivity, use 8330D. For a longer working time, use 8331S.
