RBC-3700 System is a semi-flexible, unfilled epoxy system, most often used as an epoxy potting compound. RBC-3700 offers excellent shock resistance and electrical properties and its low viscosity and long pot life lend to its excellent handling properties. RBC-3700 is an elevated cure system which makes it an excellent impregnating, potting and encapsulating system for transformers, coils, and other components requiring excellent physical shock resistance.
