- 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
