Storage & Handling
- Shelf Life
- Tack Life: 14 days tack life at 25°C (77°F)
- Out Life: 30 days at out life 25°C (77°F)
- Frozen Storage Life: 12 months at -18°C (< 0°F)
Tack life is the time during which the prepreg retains enough tack, drape, and handling for easy component lay-up. Out life is the maximum time allowed at room temperature before cure.
