- Applications
- Remove material from cold storage at least 20 hours prior to use to allow for stabilization at room temperature. Keep the DA 409U/G35-150 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 250°F.

Technical Details & Test Data
- Cure Cycle
The prepreg may be cured using either standard heat-up methods or by in-hot, out-hot press applications, other curing methods may be used such as vacuum bagging or auto clave . A pressure of 30 psi is recommended, however pressures of 10 to 50 psi may be used.
Storage & Handling
- Shelf Life
- 6 Months (40°F), 1 Year (0°F), 30 Days (75°F)
- Storage
DA 409U/G35-150 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.
