When it absolutely needs to stay on forever, Arctic Silver's Arctic Alumina premium ceramic alumina adhesive is the way to go. This high temp adhesive will ensure that the heatsink will stick to whatever you attach it to.

The ceramic composition means that there is no danger of a short circuit, unlike the silver based compounds. Arctic Alumina conducts heat away from sensitive components and improves the efficiency of your cooling system. Keep things cool and functioning under the hottest action!


Arctic Alumina Adhesive uses a layered 
composite of aluminum oxide and boron nitride.

Temperature range: 
- 40C to >150C (Bond strength is slightly weakened at temperatures below 0C due to crystallization.)

Pure Electrical Insulator: 
Arctic Alumina Adhesive is a pure electrical 
insulator, neither electrically conductive nor capacitive.

Compliancy: RoHS Compliant.
