EF2000 prepreg matrix is a complex organosilicate polymer suitable for very high temperature applications. The prepreg is typically cured at 180°C (356°F), although lower temperature cures are possible. EF2000 is intended for use as lightweight, disposable heat shields to protect composite structures for periods up to 10 hrs at 400°C (752°C) with short thermal spikes up to 700°C (1292°F). EF2000 is suitable for non-load bearing applications or lightly loaded components with well designed attachment areas. Features & Benefits: - 5 day tack life at 21°C (70°F) with both release films in position
- 15 days storage at -18°C (0°F)
- Typical cure 180°C (356°F)
- Maximum service temperature to 400°C (752°F) for up to 10 hours and short thermal spikes up to 700°C (1292°F)
