EPOCAST 50-A1/9816

Main features

  • Extended 65-Minute Gel Time
  • Solvent-Free Composite Laminating
  • Room-Temperature or Heat Cure

Product Description

EPOCAST 50-A1 Resin / Hardener 9816 Epoxy Laminating System is an unfilled, solvent-free two-component epoxy for composite structure manufacture, repair, and filament winding. The amber system mixes at 100:14 by weight and has a 65-minute gel time at 25 deg C, providing a longer application window than the 946 hardener version. It can be cured for five days at 25 deg C or heat-cured for two hours at 77 to 93 deg C after room-temperature gel. Handling and machining are typically possible after 16 to 24 hours at room temperature.

Key features

  • Extended working window: The mixed system has a 65-minute gel time at 25 deg C.
  • Solvent-free laminating system: The unfilled epoxy is used for composite manufacture, repair, and filament winding.
  • Room-temperature or heat cure: The system supports a five-day room-temperature cure or a two-hour elevated-temperature cure after gel.

Applications

  • Composite structure manufacture
  • Composite repair
  • Filament winding

Pot Life
Pot life is the amount of time it takes for the viscosity of a material to double (or quadruple for lower viscosity materials) in room temperature after a material is mixed. It is closely related to work life but it is not application dependent, less precise and more of a general indication of how fast a system is going to cure.

Thermal Properties
Glass Transition Temperature (Tg)
The glass transition temperature for organic adhesives is a temperature region where the polymers change from glassy and brittle to soft and rubbery. Increasing the temperature further continues the softening process as the viscosity drops too. Temperatures between the glass transition temperature and below the decomposition point of the adhesive are the best region for bonding. The glass-transition temperature Tg of a material characterizes the range of temperatures over which this glass transition occurs.
68 °C
