Silicone Resins – Reliable Insulation and Protection in the Most Demanding Applications
The Resins section covers advanced silicone materials designed for impregnation, electrical insulation, thermal protection, and structural reinforcement of technical components and assemblies. These solutions are engineered for long-term operation in conditions where standard organic resins fail to provide sufficient durability, parameter stability, or operational safety.
WACKER’s portfolio features silicone resins from the SILRES® family, widely used for winding impregnation, high-temperature component insulation, and electrical machinery protection. They are characterized by exceptional thermal resistance, excellent dielectric stability, and resistance to moisture, oils, chemicals, and aging processes. Thanks to these properties, they are extensively used in electric drives, generators, transformers, traction motors, and e-mobility systems.
In addition to classic impregnating resins, other specialized WACKER silicone resins are available, tailored to specific technological processes and application requirements. These include solutions for ultra-high-temperature operation, systems optimized for dipping and VPI (Vacuum Pressure Impregnation) processes, as well as resins used in electrical engineering, power generation, and heavy industry, where insulation reliability over a long device lifecycle is critical.
A common feature of WACKER silicone resins is parameter repeatability, long-term stability, and process safety. Solvent-free or low-solvent formulations support modern, more sustainable manufacturing technologies, while excellent flowability and penetration capabilities enable effective gap and winding structure filling. The result is improved heat dissipation, mechanical stabilization of components, and a significant extension of the service life of entire assemblies.
Resins from this category are chosen by OEMs as well as service and maintenance facilities that expect proven, certified solutions adapted to rigorous industry standards. These are materials that not only protect components but genuinely impact the reliability, safety, and energy efficiency of equipment.
