EPOCAST® 1627-2

EPOCAST® 1627-2 Epoxy Syntactic is a high-performance, filled, structural core-reinforcing compound with an extremely low coefficient of thermal expansion, making the material suitable for use in fabricating and reinforcing composite structures. The epoxy syntactic is supplied as a gray-colored, frozen patty (32 or 64 in³ / 524 or 1049 cm³) or Semco cartridge (6 oz or 32 oz), which is ready to use after thawing and does not require weighing or mixing. EPOCAST® 1627-2 is qualified to BMS 5-21, Type 2, specification.

Processing Guidelines

Thaw EPOCAST® 1627-2 for 1.5 to 2 hours at room temperature in its original sealed bag to prevent any contact with condensing humidity. Remove from packaging and apply to desired surface. Thawed EPOCAST® 1627-2 may be used for up to 48 hours depending on ambient temperature and if it is protected from moisture at all times. If refrozen, work life will be reduced accordingly.

 

Parameter Value
Work life, at 77°F (25°C), hours 24
Typical Cure Cycles*

1 hour at 350°F (177°C)

Typical Cure Cycles*

6 hours at 250°F (121°C)

Typical Cure Cycles*

3 - 4 days at 180°F (83°C)

Each cure cycle must include 5 - 7°F (3 - 4°C) per minute heat rise from room temperature to cure temperature, holding at cure temperature for designated time, followed by 5 - 7°F (3 - 4°C) per minute heat reduction to 150°F (66°C) or below. Cure temperature refers to temperature of material as determined by thermocouple.
