Highly Electrically Conductive Dual-Component Epoxy, Silver, 6ml Dual Syringe
8331S is an electrically conductive, silver-filled 2-part epoxy adhesive with a long working time. It is smooth, non-sagging, thixotropic, and bonds well to a wide variety of substrates. It can 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. It provides excellent EMI/RFI shielding and is very effective in filling seams between metal plates. 8331S has been formulated to be economical.
