CYCOM® E773/E773FR resins are controlled flow epoxy systems with a large processing window. They exhibit excellent high temperature performance up to 180°F (82°C) wet service temperature. The systems have good retention of tack and drape up to 20 days at room temperature in prepreg form. A straight two hour ramp cure in either a press or an autoclave may be used. No post-cure is requirement to achieve service temperature. Features & Benefits: - 250°F (121°C) cure
- 180°F (82°C) wet service temperature
- Low exotherm profile
- Controlled flow
- Large processing window
- Available in both flame retardant (FR) and non-flame retardant grades
- Autoclave or press mold processing
- Available in unidirectional tape, fabric, roving, slit tape and cross-plied forms
- History of performance on helicopter blades and other structural components
- Shelf life of 12 months at 0°F (-18°C), 20 days at 72°F (22°C)
Applications: - Helicopter blades
- Other aircraft structural components
