Safety & Health
- Product Safety And Shelf Life
Product Safety:
Observe established precautions for handling epoxy resins and fibrous materials. Ensure adequate ventilation and wear gloves and protective clothing.
Shelf Life:
- Out Life: 5 days at 18°C (64°F)
- Storage Life: 12 months at -18°C (0°F)
Out life is the maximum time allowed at ambient temperature before cure. To avoid moisture condensation: Following removal from cold storage, allow the prepreg to reach room temperature before opening the polythene bag. Typically, the thaw time for a full roll of material will be 4 to 6 hours.
