6979
Astro 6979 is a pourable, two-part epoxy potting and encapsulation compound formulated for high thermal resistance and to minimize physical stress on adjacent insulation materials caused by thermal expansion.
This epoxy system is frequently used to encapsulate stator series loop connections in the bottom caps of bar-wound generators.
