EPOCAST® 89537 A/B

EPOCAST® 89537-A/B epoxy syntactic is a two-part system with glass-fiber reinforcement that can be troweled or extruded into honeycomb core structures for fastener and attachment potting, core splicing, and edge reinforcing. The syntactic has a non-sag consistency that allows for vertical application up to ½-inch (1.25 cm) thick. EPOCAST® 89537 A/B epoxy syntactic is self-extinguishing and meets the requirements of BMS 5-28 Type 32.
