Default Anyone have thermal epoxy?

Anyone have some thermal epoxy (Preferably Arctic Silver) they could sell to me for cheap?

Default Re:  Anyone have thermal epoxy?

I searched and didn't find anything under thermal epoxy. I can't use regular thermal paste/compound (The kind used for CPU's) as I need the adhesiveness of epoxy. The cheapest I've seen on eBay is for $12 shipped.

Default Re:  Anyone have thermal epoxy?

its a bit expensive, forgot what they called it but arctic silver has some - I think you can buy it off newegg.com and I know you can get it from SVCcompucycle. I've also heard of people mixing epoxy with regular thermal paste for a poorman's thermal epoxy. Dunno how effective that one is though.

Here's the goop you need:

Works well. If you don't have access to a lathe - or a welder - it allows you to still make a decent heatsink with parts from a hardware store.

assuming that its made with silver... does thermal epoxy act as a conductor to electricity?

Default Re:  Anyone have thermal epoxy?

I'm sure you can get thermal epoxy in conductive and non conductive variants. Normally though, you'd want it to be non conductive and non capacitive. Here and there I've worked with this colloidal silver paste that does use suspended silver and is actually intended for electrical conductivity, but I bet itd be pretty good with thermal conductivity too. Its incredibly expensive though - and not just because of the silver content.

basically just wondering because i would like to heat sink my Aixiz modules with the pen hosts that surround them in my builds. however some of my builds i have the negative current running through the host... so i'd like to keep the heat conductivity as well as keeping the electrical circuit complete.

Default Re:  Anyone have thermal epoxy?

Sometimes I wonder why I bother posting here. The thermal epoxy I linked to is over 60% silver by weight, it's designed to conduct heat, not electricity.

For those that can't be bothered to read, it says: "Superior thermal conductivity. Greater than 7.5 W/mK" - "Arctic Silver Thermal Adhesive was formulated to conduct heat, not electricity. ". from http://www.arcticsilver.com/arctic_s...l_adhesive.htm

Bye

Default Re:  Anyone have thermal epoxy?

sorry flogged, that is the same stuff I was talking about but too lazy to link. I thought the question was generally asking if thermal epoxies could be electrically conductive, or more specifically, if he could purchase a paste that was both thermally and electrically conductive, so I figured those kinda superceded the one specific type of epoxy in your link
