Duronaut is a high-end thermal compound that was developed with a focus on excellent thermal conductivity and particularly high long-term stability. The name "Duronaut" is derived from the term "durability". This exceptionally high long-term stability is achieved through a specially developed silicone oil and the combination of aluminium micro-powder and zinc oxide nano powder in various forms. The optimised particle shape and size minimise the so-called pump-out effect and ensure excellent adhesion of the paste to the surface. This results in extremely low heat transfer resistance.
