J B Weld - thermal properties??

plywood99 · 04-25-2005, 08:44 PM

Anyone know the thermal properties of J B Weld? I read an article on overclockers where a guy used it for a tim joint and had good results.

I'm not using it for a tim but for something moldable needing good thermal properties.

Thanks in advance...

Just about anything works in a thin enough layer.

It's not likely to be amazing, try AS adhesive if you need an epoxy with thermal properties.

The amount I would need makes it cost prohibitive.

It's not electrically conductive, which, using someone else here's tip, would indicate that it more than likely has poor thermal properties. I just went over the site, and as expected, no info.

Might I ask what you are using it for? Myself or others might be able to suggest alternatives if you tell us what it is for.

According to the JB weld's resin's MSDS, it contains 10-20% iron (why isnt it conductive?)

I dunno, you could try adding copper dust or something like that in with it.

Actually, that is kinda what I will be doing, but using a something besides copper dust. J B Weld will only make up about 5% - 10% of mass.

MaxSaleen, I'm trying to tie several heat sources into one common tim that must be formable. Not trying to be secretive, just a project I'm working on...
