Details
Arctic Ceramic Epoxy (ACE) is a two-part permanent thermal adhesive from Arctic Silver. It bonds heatsinks to components where clips, screws or other mounting hardware cannot be used, and its fillers are ceramic: aluminum oxide and boron nitride. This 6-gram set holds the resin and the hardener in two separate 3 g syringes.

Permanent thermal bond
Arctic Silver describes ACE as a permanent thermal adhesive. Once it has cured the heatsink stays where it is, so use it for parts that are meant to stay attached for good, such as small heatsinks on RAM, voltage regulators, chipsets and other ICs.
Ceramic fillers
Next to the epoxy resin, the safety data sheet lists aluminum oxide (40 to 50%) and boron nitride (10 to 20%) as the components. These are the ceramic fillers Arctic Silver uses in its ceramic thermal epoxies.
Easy 1:1 mix
Arctic Silver gives its ceramic thermal epoxies a 1:1 mix ratio of resin (A) to hardener (B), dispensed from Luer slip syringes and cured at 25°C (77°F). Equal amounts from the two syringes are all you need.
How to apply it
- Clean both surfaces so they are dry and free of grease and residue; isopropyl alcohol works well.
- Dispense equal amounts of resin (A) and hardener (B) and mix them thoroughly until the color is even.
- Spread a thin, even layer on one surface; avoid thick layers.
- Place the heatsink carefully and hold it still. The bond is permanent once cured.
Handle it safely
The safety data sheet classes the uncured epoxy as a skin and eye irritant that may cause an allergic skin reaction or irritate the airways. Wear gloves and eye protection, work in a well-ventilated area, wash your hands afterward and keep the syringes out of reach of children. Part A has a slight epoxy odor, part B a sulfur (mercaptan) odor.

Notes
- This is a permanent adhesive, not a thermal paste for mounting a CPU cooler. Use a thermal compound such as Arctic Silver 5 or Céramique 2 there.
- Close both syringes tightly after use and store them in a well-ventilated place.
