Product Details:

For over two decades, 8331 has been our flagship product. 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 SVHC’s 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 8330 or 8330D. For a longer working life, use 8331D or 8331S.

For a 1-part alternative use 9410 or 9400.

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

Product Details:

A silver conductive pen that dispenses acrylic lacquer pigmented with highly conductive silver flakes. The cured traces are durable, corrosion resistant, and highly conductive. They adhere well to plastics and most electronics substrates. The valve tip opens when pressed against a surface, and the flow is controlled by squeezing the barrel. The product works best on a smooth, flat, hard surface, but the cured circuits are highly flexible.

This conductive pen can draw electrical circuits for prototyping, hobbies, or maker projects. It can also repair damaged circuits on keyboards, game controllers, remote controls, mixing boards, and PCBs. It can also make small connections in or between circuits, such as jumpers, through-holes, and bridges. As well, it can be used to increase the surface areas of contacts by painting the area around them.

This product is our best conductive pen. For applications where high conductivity is not required, the 838AR-P Carbon Conductive Pen and the 841AR-P Nickel Conductive Pen provide economical alternatives. This product is also available in liquid and aerosol formats.
