RBC-4100 is a highly filled, thermally conductive epoxy resin designed for applications requiring excellent electrical insulation, high heat dissipation, and low shrinkage. This resin offers excellent resistance to filler settling during storage and may be heated to 140oF to reduce viscosity prior to catalyst addition. RBC-4100 can be cured at room temperature or elevated temperatures to fit a variety of applications. It can be used as heat sink for large castings or as an encapsulant for heat generating components.

(Note: The above properties are typical of a system cured with epoxyhardener #AB-312.)


RECOMMENDED HARDENERS:

A-110: A rigid, room temperature curing system with limited pot life and fast cure.
A-122: 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 #4100 Resin into a clean container and combine with recommended hardener in one of the ratios shown below.
