Duronaut is a high quality heat conductivity paste characterized by outstanding thermal conductivity and long life. Durability is provided by specially developed silicone oil, which is combined with aluminum mikroravia and various shapes of zinc oxide nanoparticles. Optimized particle shapes provide excellent adhesion on the surfaces, but they guarantee extremely low heat resistance and apply it in a thin layer. The redesigned spatula allows for greater pressure during the application so that the paste is more efficiently distributed and a thinner layer can be created.
