RBC-3200 Resin

RBC-3200 is a modified, low-viscosity epoxy potting compound offering excellent wettability and air release. It is similar to #3100 in versatility, but by comparison offers longer pot life, greater impact resistance, and improved handling characteristics. #3200 Resin can be used for epoxy potting and encapsulating, epoxy casting, epoxy impregnation and other applications where a low viscosity epoxy system is desirable.

(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 #3200 Resin into a clean container and combine with recommended hardener in one of the ratios shown below.
