Generally, their dielectric properties associated with a good level of thermal conductivity of the corresponding formulations make them especially well suited for high-performance electrical insulation, without heat accumulation. Compared to other materials used with the same functionality like Polyurethane, their thermal resistance creates a huge advantage, and the fire resistance, which is commonly required in the protection of electronics systems, is outstanding in the case of silicone formulations. Finally, compared to other materials like epoxy resins, silicones offer the advantage of an extreme flexibility creating no stress during differential dilatation on the electronic components (Silicone Gels are even better on this specific property). Resistance characteristics include the ability to withstand long periods of exposure to severe atmospheric conditions. They also have good mechanical properties and their low surface tension enables them to properly reproduce surface detail, making them a material of choice for Molding applications. Many RTV-2 formulations provide an efficient release effect, more than cured rubbers have for organic and inorganic materials. They are ideal materials for molding, printing and prototyping applications.
