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. | HANDLING PROPERTIES: | Mixed Viscosity @ 25oC, cps

(Note: The above properties are typical of a system cured with hardener #AB-312.)
RECOMMENDED HARDENERS:
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.
MIXING INSTRUCTIONS:
Weigh the desired amount of #3600 Resin into a clean container and combine with recommended hardener in one of the ratios shown below.
