RBC-3412 Techincal Data Sheet

Type :

Electronics

RBC-3412 is a filled, thixotropic, general purpose dip coating epoxy resin. Its’ physical and electrical properties are similar to #3300 Resin, but #3412 is can be used for dipping and coating transformers, coils, capacitors, etc. RBC-3412 can be cured at room temperature or elevated temperatures, depending upon the hardener selected and the heat resistance of the part.

(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.
