Epocast_8623-A/9861 Low Density Potting Compound
Epocast 8623-A/9861 is a two part epoxy core filling compound. It has a soft paste viscosity developed for easy extrudability through a 1/8" nozzle. The compound is self-extinguishing and cures at room temperature if desired. Elevated temperature cures or post cures will improve elevated temperature properties.
