RBC-3600 is a low-viscosity, low density, filled epoxy potting resin (epoxy potting compound) used where lightweight castings are necessary without the loss of acceptable physical and electrical properties. RBC-3600 possesses excellent air release and good flowability producing void-free castings. It is especially useful in the aerospace and automotive industries where increased emphasis is placed on high performance from lightweight components.

(Note: The above properties are typical of a system cured with hardener #AB-312.)
A-110: A rigid, room temperature curing system with limited pot life and fast cure.
A-120: A resilient, low viscosity system with slightly longer pot life, that exhibits excellent resistance to thermal shock.
AB-312: Good resistance to heat, chemicals, thermal and mechanical shock, and good electrical properties at high humidity.
