Reliable thermal transfer
My CPU temps dropped by about 4 degrees after replacing the old dried paste with this silicone gel. It cures nicely and doesn't pump out over time. Highly recommend for general electronics cooling.

Decent but messy application
The product works fine for thermal conduction, but I found it a bit messy to apply precisely. Make sure to have some cleaning solution ready. Once cured, it performs well though.

Good insulation properties
Used this on some old transistors in a power supply repair. It provides excellent electrical insulation and seems to handle the heat well. Only giving 4 stars because the tube nozzle is a bit wide for very small components.

Perfect for my Ender 3 hotend
This gel works exactly as described. I applied it to the throat tube heatsink on my 3D printer, and the temperature stability improved immediately. The milky white paste spreads easily and adheres well without dripping.

Great value for 5g
For the price, you get a good amount of product. I've used it on multiple projects including LED drivers and motor controllers. The milky white color makes it easy to see where you've applied it.

Strong adhesion as advertised
I was worried about the gel shifting over time, but the strong adhesion claim is accurate. It stays put even under vibration. Great for securing small heatsinks on chips where screws aren't an option.
Q: What is the shelf life if unopened?
A: When stored in a cool, dry place with the cap tightly sealed, the unopened tube has a shelf life of approximately 12 months from the date of manufacture.
Q: Does this require mixing before use?
A: No, this is a one-component silicone gel that is ready to use straight from the tube. No mixing or catalysts are required.
Q: How long does it take to fully cure?
A: At room temperature (25°C), the surface skins over in about 30 minutes, but full curing typically takes 24 hours depending on humidity and thickness of application.
Q: Can I use this on plastic parts of a 3D printer?
A: Yes, it is generally safe for most plastics used in 3D printing, but we recommend testing on a small inconspicuous area first to ensure compatibility with your specific material.
Q: Is this gel electrically conductive?
A: No, this silicone gel is designed to be electrically insulating, making it safe for use on live circuits and components like CPUs and transistors.
