Storage & Handling
- Storage Life
- Tack Life: 13 days at RT (23°)
- Out Life: 15 days at RT (23°C)
- Shelf Life: 12 months at -18°C (from date of manufacture)
Tack Life: The time, at room temperature, during which prepreg retains enough tack for easy component lay-up.
Out Life: The maximum accumulated time allowed at room temperature between removal from the freezer and cure.
Shelf Life: The maximum storage for HexPly® prepreg from manufacture, when stored continuously, in a sealed moisture-proof bag, at -18°C.To accurately establish the exact expiry date, consult the box label.
