8330 – Silver Conductive Epoxy Adhesive

For over two decades, 8330 has been our flagship product. Now, after much research and development activity, we are excited to announce 8330 will be replaced by an improved version, 8330D. 8330D 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, 8330D offers improved conductivity and flowability. It also provides higher safety, being free of SVHC’s and no Proposition 65 listed ingredients

8330 is a 2-part epoxy electrically conductive glue. It is smooth, non-sagging, thixotropic, and bonds well to a wide variety of substrates.

This silver conductive glue 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.

8330 is an electrical adhesive that is highly filled to maximize electrical conductivity. For a more economical version, use 8331 or 8331D. For a longer working life, use 8330D or 8330S.

For a 1-part alternative use 9410 or 9400.

We also offer a full line of thermally conductive electrically insulating epoxy adhesives.
