Storage & Handling
- Storage Life
- Shelf Life: 12 months at -18°C/0°F (maximum, from date of manufacture).
- 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 Life: 14 days at room temperature (25°C max).
- The maximum accumulated time allowed at room temperature between removal from the freezer and cure.
- Tack Life: 10 days (depending of the reinforcements) at room temperature (25°C max).|
- The time, at room temperature, during which prepreg retains enough tack for easy component lay-up.
- Storage
HexPly® M81 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 its packaging can take up to 48 hours).
