10g Thermal Conductive Silicone Plaster Viscous Adhesive Compound Cooling Glue For LED GPU Chipset Heatsink

Works as advertized. (I used it to glue and seal a heat exchanger). Takes a few hours to set and forms a strong bond. Would help to have detailed spec sheet giving thermal conductivity.

good quality glue for heat sink of processor etc

This glue ruined my chipset

Had to use this with an crypto miner that needed new heatsinks and never experienced a problem since then

This thermal glue is great. It glues the heat sink to the IC very tight. In my experience, the curing time is very long. Over one week to fully cure. I do not regret buying it. I have used it with several ICs since I purchased it. The fluid is still good inside the tube even months after opening. I though it would be hardened by now, 9 months after opening. The fluid is not a paste, I would say, it is medium thick fluid. It does not run and it is easy to apply. A small application works great.

I purchased this adhesive in June 2018 and first used it over the past couple of days to assemble homemade heat sinks and apply them to NVME SSDs. Before bonding parts I applied the adhesive to lapped 1/2" square pieces of 1/16" thick aluminum 1100 and applied moderate pressure. A joint gap of .001" was measured with calipers. At a thermal conductivity of 1.2 W/m-K, this bond thickness has neglible thermal resistance for my application. Bonding of parts was done at a humidity of ~30% and a temperature of ~70°F. The adhesive did not "skin over" or otherwise exhibit an increase in viscosity during the fifteen minutes or so that I was working with it. I prefer a slower curing adhesive so that I do not have to race to get parts assembled before increased viscosity causes problems. This applies in particular to parts being bonded to circuit board components since large clamping forces have the risk of damaging the circuit board. Silicone (polysiloxane) adhesives require moisture to cure and this moisture can be provided from the atmosphere or adsorbed moisture on surfaces that are being bonded. Thin joints will cure faster than thicker joints. If you are not going to be able to leave the bonded parts alone for at least 24 hours, it is a good idea to bond pieces of scrap metal and/or plastic and test the bond strength of the test pieces prior to putting your bonded assembly into service. Cleaning surfaces to be bonded with a cotton swab and isopropanol and/or acetone (not suitable for some plastics) is also recommended since the solid filler used to enhance thermal conductivity inhibits the flow and wetting capability of the silicone adhesive. TANSTAAFL. Two pieces of copper were cleaned, bonded, and tested after a 24 hour cure (see photo). The lap joint (~.3 sq.in.) held up under the application of a 10 pound shear force, but failed at 20 pounds. The adhesive in the interior region of the failed joint was still plastic, indicating that the joint wasn't fully cured; however the bond was strong enough for my application.

Worked great 👍 👌

Originally I saw that this was only 10 grams and debated buying multiple. 1 tiny tube was way more than enough! I ended up with a lot of extra and was running around my house adding heat sinks to anything that gets even remotely warm just to use up the tube and avoid wasting the rest of it. After adding heat sinks to my 3D printer’s stepper motors, two raspberry pi 3Bs, one Raspberry pi 4, a couple Arduinos, and other miscellaneous electronics, im still left with about 75% of the paste still in the tube! The paste works great. I wouldn’t use this on anything that you intend to eventually take apart like a PC or anything, but for adding heat sinks and creating permanent bonds, it’s amazing! If I was describing this product to someone that had no idea what it was, I’d describe it as a “thick super glue made to move heat on electronics”. The dry time was a lot faster than expected. If used correctly where you press out all the excess and wipe it off, it took maybe 2 hours to fully stick, after sitting overnight I doubt anything will be able to pull those heat sinks off.
