Storage & Handling
- Shelf Life
- Tack life at 95°F (+35°C) 3 days and at 73°F (+23°C) 5 days
- Guaranteed shelf life* at 73°F (+23°C) 4 weeks and at 0°F (–18°C) 12 months
- Storage
HexPly® M27 prepregs should be stored as received in a cool dry place or in a refrigerator. Following removal from refrigerated storage, allow the prepreg to reach room temperature before opening the polyethylene bag to avoid moisture condensation. (A full reel in its packaging can take 48 hours.)
- Product Handling and Safety
Hexcel recommends that customers observe established precautions for handling uncured synthetic resins and fine fibrous materials. Operators working with this product should wear clean, impervious gloves to reduce the possibility of skin contact and to prevent contamination of the material.
