- Applications
- Remove material from cold storage at least 20 hours prior to use to allow for stabilization at room temperature. Keep the material wrapped to prevent moisture from condensing on the adhesive. Cut the prepreg to size, remove the poly separator and apply to part or mold. Remove separator paper. Continue process until the desired number of plies are obtained. When lay-up is complete, the prepreg can be cured in a vacuum bag in an oven or autoclave. Apply at least 10 psi pressure and cure for one hour at 200°F.

Technical Details & Test Data
- Cure Cycle
The recommended cure cycle for DA 4080 and DA 4082 Prepregs is one hour at 200°F at 20 psi.
Storage & Handling
- Shelf Life
- 1 Year (0°F in a Sealed Container), 6 Months (40°F), 20 Days (75°F)
- Storage
Store material in a contaminate free container and store at O degrees F for extended storage. For shorter storage time requirements store at 40 degrees F, this enables quicker stabilization times.
