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
