EPOCAST® 1618 D/B

EPOCAST® 1618-D / B epoxy syntactic is a low-density, flame-retardant compound for potting fasteners in honeycomb structures. The lightweight epoxy is easy to extrude through a 1/8 in (3 mm) nozzle orifice but is non-flowing after application. Epocast® 1618 D/B epoxy syntactic sets quickly at room temperature and is qualified to BMS 5-28, Type 18, Class 1. It is the suggested alternative for the discontinued Epocast® 1616 A/B epoxy syntactic, Epocast® 1618 A/B epoxy syntactic, and Epocast® 1620 A/B epoxy syntactic systems.
