Now, after much research and development activity, we are excited to announce 8331 will be replaced by an improved version, 8331D. 8331D offers improved productivity, curing at room temperature in only 5 hours instead of the 24, while offering twice the working time, 20 minutes instead of the old 10 minutes. As well, 8331D offers improved conductivity and flowability. It also provides higher safety, being free of SVHCs and no Proposition 65 listed ingredients. 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 conductive epoxy 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. It provides excellent EMI RFI shielding and is very effective in filling seams between metal plates. 8331 has been formulated to be economical. For a higher fill that maximizes conductivity, use 8330D. For a longer working life, use 8331D or 8331S. For a 1 part alternative use 9410 or 9400.
