RBC-3610 epoxy resin is a thixotropic version of RBC-3600 epoxy resin/epoxy potting compound. It offers the same physical and electrical properties obtained with RBC-3600 epoxy resin. It is especially useful in the aerospace and automotive industries where increased emphasis is placed on high performance from light weight 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.
Weigh the desired amount of #3600 Resin into a clean container and combine with recommended hardener in one of the ratios shown below.
