Storage & Handling
- Storage Life
- Shelf Life¹: 12 months at -18°C/0°F (from date of manufacture).
- Shelf Life: The maximum storage life for HexPly® prepreg, when stored continuously, in a sealed moisture-proof bag, at -18°C/0°F or 5°C/41°F. To accurately establish the exact expiry date, consult the box label.
- Out Life2: 30 days at room temperature (25°C max).
- 2 The maximum accumulated time allowed at room temperature between removal from the freezer and cure.
- Tack Life: Up to 30 days (depending of the reinforcements and the resin content) at room temperature (25°C max).
- Tack Life: The time, at room temperature, during which prepreg retains enough tack for easy component lay-up.
- Storage
HexPly® M49 prepregs should be stored as received in a cool dry place or in a refrigerator. After removal from refrigerator storage, prepreg should be allowed to reach room temperature before opening the polythene bag, thus preventing condensation (a full reel in it’s packaging can take up to 48 hours).
