Looking fo thermal adhesive

[Jason Robinson]

Does anybody know of a place in town that you can buy thermal adhesive?  Here is an example of what I need, http://www.newegg.com/Product/Product.aspx?Item=N82E16835100013.

Thanks,
Jason

Have you tried Fry's Electronics?

Fry's electronics... I've only been in the phoenix area for about a year so I'm not familiar with them.  Thanks, I'll take a look.

Dang, they have it but only for online order.

Didn't research, but http://www.circuitspecialists.com/ is local; you've gotta browse online and tell them exactly what you want though.

Another great place to add to my list.  Thanks!

How much do you need? I may have some extra.

Enough for 12 star base LEDs.  They have a 3/4" diameter.  So, not much.

Are you *sure* Fry's doesn't sell thermal glue?  I'd go down there and look, they have got a LOT of things.

I'll give them a call...   Ya, turns out their website was right, but at least they will be getting some in about a week.

Jason, just to make sure i understand. You are looking for a glue or adhesive, like a special thermally conductive epoxy, not the thermal paste used between a CPU and its cooler? Staples claims to sell the thermal paste, and that will carry the heat away from your LEDs, if something else holds them down.

Ya, you're right. If I had another way to secure them then thermal paste, which I already have, would suffice.  They are going to be placed on a metal sheet to dissipate heat.  I was going to drill holes and use twisty ties to hold them down, but they would have to be resistant to melting and coated thick enough that shorting the circuit wouldn't be a concern.  I thought thermal adhesive made more sense.  Any ideas?

    Yes, you could use something for fixing cracks in Franklin stoves, or fireplaces. That you can probably get at ACE Hardware, Home Depot, Lowes, but will likely come in black, black, and black. Or something for automobile engine repair or exhaust. That would be an Autozone, Checkers (now called something else) or Pep Boys. Another possibility is model airplane supplies. They should have some glues for around the engine parts that would be high temp. I wonder if appliance parts stores would have a high temp adhesive for oven, hot water heater, dryer or other parts, like over temp thermoswitches.

   To do something more thermal conductive would be to go to a large hardware or auto parts store, look for an epoxy that is rated for higher temps (250F, 125C or higher), then mix in some aluminum or copper filings to help conduct the heat away better.

Another online source would be McMaster-Carr

Thanks, I appreciate the suggestions!  Tim M mentioned he might have some extra so I'll check with him, otherwise I'll just order some.  I thought I needed it immediately, but I might be able to make regular thermal compound work for now.
