Packaging & Availability
- shipping
- Prepreg fabric and tape are generally shipped in sealed polyethylene bags in insulated containers packed with dry ice.
Storage & Handling
- Storage
HexPly® F584™ prepreg should be sealed in a polyethylene bag and refrigerated, preferably below 32°F (0°C). Following removal from refrigerated storage, allow the prepreg to reach room temperature before opening the polyethylene bag to avoid moisture condensation. Shelf life: 6 months at 0°F (–18°C), 3 months at 40°F (4°C) (maximum, from date of manufacture).
- Product Handling and Safety
Hexcel recommends that customers observe established precautions for handling epoxy 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.
