- Quick Setting
- Self Extinguishing
Epocast® 1618 D/B Epoxy Syntactic is a low-density, self-extinguishing compound for potting fasteners in honeycomb structures. The lightweight epoxy is easy to extrude through a 1/8 in (3mm) 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 Epocast® 1616 A/B Epoxy Syntactic, Epocast® 1620 D/B Epoxy Syntactic systems.
