RBC-4590 resin and AB-440 is a two component, filled, low viscosity, flame-retardant semi flexible epoxy/urethane elastomer system suitable for potting and encapsulation.
The cured system has excellent moisture resistance, electrical properties, and thermal shock resistance. The 1:1 volumetric mix ratio characteristic of this system makes it ideal for automatic mixing and dispensing.
