Arctic Alumina Thermal Adhesive

Arctic Alumina Thermal Adhesive is a two part adhesive for thermal joints in minimum bond line applications.  The surface area of any heatsink is not perfect. This ensures maximum thermal transfer between the LED Star and Heatsink. This is semi permanent as the LED Star can be removed with a light tap with hammer and chisel. This can also be used to secure the Carclo Universal Optic Holder. For proper use refer to the instructions here.

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.


RoHS Compliant.

A set of Arctic Alumina Thermal Adhesive consists of two syringes containing a total of 5 grams of adhesive (2.5 grams each of parts
A and B) and a plastic reusable mixing wand. Approximately 3cc total adhesive.

Although lighter per set than Arctic Silver Adhesive due to its use of ceramics rather than silver, each set of Arctic Alumina Adhesive
contains the same amount of adhesive by volume as a set of Arctic Silver adhesive and will cover the same area.

Arctic Alumina Thermal Adhesive should be kept cold and away from UV light (sunlight and florescent lighting). We recommend refrigerating the unused material and allowing it to come to room temperature prior to use.

Arctic Alumina Thermal Adhesive is a permanent adhesive. Components you attach with Arctic Alumina Thermal Adhesive will
stay attached forever unless you remove them with moderate force.
