UL APPROVED – FLAME RETARDANT
THERMALLY CONDUCTIVE COMPOUNDS
These UL Approved thermally conductive Compounds are pourable, room temperature cure, epoxy resin systems. They are ideally suited for meter mix dispensing and designed for medium voltage devices such as transformers, electronic modules, and coil. They can also be used for many other general purposes of potting and encapsulating applications.
