Technical Details & Test Data
- Technical Details
Packaging & Availability
- shipping
- Prepreg is generally shipped in a sealed polyethylene bag in refrigerated transportation or in containers with dry ice.
Storage & Handling
- Product Handling and Safety
Hexcel recommends that customers observe established precautions for handling 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.
- Storage
3501-6 prepreg should be sealed in a polyethylene bag and refrigerated, preferably below 32°F (0°C). Following removal from refrigerated source, allow the prepreg to reach room temperature before opening the polyethylene bag to prevent moisture condensation.
- Shelf Life
- 12 months at 0°F (–18°C)
- 4 months at 40°F (4°C)
- 10 days at 70°F (21°C)
