Wire glue (Conductive glue)

Quote

For example, the approximate rho for this stuff is 0.36 ohm inches.
This means that for a bar with circular cross section that is 1 inch
long and has a diameter of 1/16 inch the total resistance from end to
end is 118.7 ohms.

It turns out that it's approximately 0.36 ohm inches for this stuff
after it dries, and wow, that's over 500,000 (five hundred thousand)
times higher than copper! Yikes. This means the emulsion must
be playing a big part in the conductivity rather than the carbon.

It still seems to be usable though because for a diameter of 1/16
inch and only 0.01 inches thick (like a typical connection might
be made) the total resistance would only be a little over 1 ohm,
which isnt that bad, and as Bigglez pointed out, some things could
easily stand this kind of higher resistance, and as he also pointed
out, stuff like this could make the repair of such things possible
when otherwise not. I myself first thought of remote controls
that have keypads that break down and cant be soldered to fix.

Just for fun i made a home made resistor that was about 3/8 inches
long and measured around 250 ohms, and used it to limit current
to a white LED driven from a small 9v battery. The current was
14ma so at least i know this stuff works at low current and
the manu states low voltage too so 120vac stuff is out.
On the downside, it seems to act as a very poor tolerance resistor
because it's resistance changes 10 percent over the temperature
range of 85 deg F to 180 deg F. Thermistor anyone? ha ha.
It might however stablize better at some temperature cycles later,
as yet to be determined, as there was an indication during
the test that this would happen at least to some degree.

Oh yeah, it's water based too, so you can mix it with water
to make it less thick. As it comes, it's a rather watery
paste that runs easily, but more like thick paint than
toothpaste. The drawback is that it may break off of
surfaces like copper, etc., because it reminds me of
dried clay after it dries. I hope this isnt too much
of a problem. But, applying an overcoat of epoxy
might help too, and the manu suggest superglue, but
then i dont know if i would use that myself.

Compare with crappy $25 silver based stuff: Wire Glue has 2x lower rho (better)
Compare with 38 dollar silver based stuff: Wire Glue has 100 times higher
rho (worse)
Thus this Wire Glue is better than the crappy silver stuff (surprising)
but much worse than the better silver based stuff (as expected).
