HY910 20gram Thermal Conductive Glue, High-Performance Thermal Plaster, Silicone Viscous Adhesive Cooling Compound, Heatsink Glue for GPU LED MOSFET 3D Printer IC Chipset

I used this to glue some large heat sinks to an LED array's aluminum panel and it worked great. I have no way to test the thermal conductivity but the light runs much cooler now and the heat sinks get hot so it must be transferring the heat. Better than thermal grease if you want your heat sink to stay in place permanently.

works great!

Great item, fast shipping, good safe packing

I'm using this thermal glue to bond a metal temperature sensor to an aluminum resin tank on a 3D printer and so far it's working well. As it says in the title, this "HY910 0.975W/m-k Thermal Conductive Glue" works to bond components to surfaces. Although not super strong like epoxy, it does provide a decent bond that seems secure and it transfers heat well. The glue I got took much longer than 30 to 45 minutes to really firm up, it was more like a couple hours. It also doesn't seem to get rock hard like epoxy, but it does get pretty firm. With that said, I would recommend this thermal conductive glue if you have something you need to attach to a surface where heat conductivity is required. It does seem to work as advertised. (And to be clear, the probe I'm using isn't actually sitting in the resin- it's glued/mounted to the *inside* of the hollow frame of the resin tank. Neither the probe nor the glue ever come into contact with the resin. A silicone 'band heater' is wrapped around the outside of the tank, controlled by a cheap $3 temperature controller. After everything comes up to temperature, the inside of the aluminum frame is within ~0.5 degrees C of the resin's actual, dip-tested temperature, more than close enough for temperature control.)

Worked fine for my project.

Never cured. Even after 24 hours just wiped right off of heatsinks with a paper towel.

After sitting overnight over 12 hours, this Halnziye HY910 thermal "glue" is about like ordinary white bathroom silicon caulk on the outside skin, but still a bit mushy inside. I don't know if it will work for us. Still on the hunt for a good, high temperature thermocouple bonding agent.

Used these to hold heat sinks on my excavator cylinder as I don't want to buy and stuff a heat exchanger into the hot engine bay. I thought it would need a screw or two but they are still holding on after a couple months so it works well.
