Filled and non-filled casting epoxy resins for electrical industry

Casting epoxy resins for the electrical industry within the Synpo portfolio are filled and unfilled. These are 1-K or 2K-epoxy systems with excellent crack resistance and UL94 certification. We have high and medium voltage systems in our portfolio. In addition, we also produce special systems and systems for low voltage and encapsulation or impregnation.
