Packaging & Availability
- shipping
- Prepreg is generally shipped in a sealed polyethylene bag in refrigerated transportation or in containers with dry ice.
Storage & Handling
- Shelf Life
- Shelf Life: 12 months at 0°F (-18°C) (maximum, from date of manufacture)
- Out Life: 30 days at 73°F (23°C)
- Tack Life: 10 days at 73°F (23°C)
- Storage
HexPly® M77HF 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 creel in its packaging can take up to 48 hours).
