RBC-3710 is a filled, high viscosity version of RBC-3700 which exhibits greater tensile and compressive strength. It offers a long pot life at elevated temperatures which insures good wettability and impregnation. Like RBC-3700, it is primarily an epoxy potting compound but it is also an excellent impregnating and encapsulating epoxy system for transformers, coils, and other components requiring excellent physical shock resistance. | HANDLING PROPERTIES: | Mixed Viscosity @ 25oC, cps

MIXING INSTRUCTIONS:
Stir epoxy resin #3710 and epoxy hardener #3710 in their shipping containers prior to each use to insure uniformity. Use of power equipment is recommended.Weigh the desired amount of #3710 Epoxy Resin into a clean container and combine with recommended amount of #3710 Epoxy Hardener. Mix thoroughly. Entrapped air may be removed by vacuum.
