Need ASIII Epoxy type substance! Dries in micro minutes?

[ol' man]

Today i made a new fandangled HS and I needed to attach something onto it kinda permanently! Being the investigative guy I am I added ASIII to super glue (with swirling and mixing) and came up with a compound similar to epoxy but dries/hardens much quicker and sticks very well with the consisency of superglue!

I know some people put super glue at the edges and ASIII is the middle but I needed something really strong! THIS WAS IT! IT dires in a matter of like 30 seconds though so you gota get on it and compress the two items together! Pretty amazing I must say!

But the super glue is detrimental to the effectiveness of ASIII

You think?

Tell me then what is the thermal conductivity of silicone oil versus super glue?

Silicone oil in ASIII and Cyanoacrylic polymer in super glue?

Basically the mix was 1/3 super glue and 2/3 ASIII. It formed a compound similar to what you find under GPU heatsinks but since it is a silver based product I would have to confer that it is much better!

Tell me also what is the difference in thermal conductivity between super glue( a cyanoacrylic polymer) and epoxy?

ASIII epoxy is only ASIII and epoxy mixed together or some constituents mainly silver mixed in epoxy!

I doubt there is much difference. The main thing is getting the bond very thin. The thinner the better. Super glue can get very thin and with ASIII mixed its thermal conductivity is going to increase most likely greatly! Anyway so far it it working like a charm on in my application!

Keep a close eye on it. It appears to be sticking alright, but might not handle thermal cycling too well.

Superglue works on different principal than epoxy. I don't think they alter thermal conductivity characteristic whole a lot of if you have plenty of silver in it. I haven't tried it though.

Ethyl cyanoacrylate polymerizes catalyzed by small amount of water. High tensile strengh, but very hard and can shatter.

Epoxy polymerizes between reactions of two parts without any outside chemicals.

I have mixed Super Glue with lots of things over the years with work with models. It tends to granulate quite a bit when mixed and the compound tends to deteriorate over time and almost crumble. I usually mixed it with a modeling puddy, but found it did similar things with paints, fillers, arisals and such. Super Glue is also an insolator not the best at thermal transfer. I'd say bonding the edges is safer to keep the Super Glue up to its full bonding strength and give the AS3 the the best possible thermal transfer. Use thin layers of both and only seal in two edges, not all the way around. This really works good. I have used this many times on GPUs, Northbridges and memory chips.

The silicone oil in the ASIII catalyzed the reaction and it got hard instantly to form a very very slightly pliable substrate!

I tried the same thing first with the old style Zinc Thermal paste and it did granulate and not work well but the ASIII did not granulate at all but instead disolved perfectly into the super glue forming a silver colored compound that when dry resembled solder! It is interesting and I would really like to know what kind of polymer this produced! This compound does not have much if any properties of super glue or ASIII!

Todd,

You mention that super glue is a good insulator! Well so is epoxy! One thing you must remember though is that the ASIII is mixed in such a way and spread very thin as to cause little problems and have very good thermal throughput! Also would liek to point out that the item in which this compound was used is sandwidched between two other flat plates!

Yes but can you spread this thicker concoction as thinly as befor. Not only it the thermal resistance likely higher do to the Super Glue, but it is also likely going to be thinker.

Put it this way. The app that I am using this for allowed me to measure the thickness. It is as thin as any asIII application.

[outside looking in]

I've never seen so many !'s in one post.

If you can keep it thin and get pressure on it befor it starts to harden, then It sould work OK. I just preffer the old way with the Super Glue allong the edge (or dots on two corners of ram sinks). Less fussy and no mixing needed.
