- 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.
- Cure Time Cycle
DA 4518 is designed to cure in one hour at 250F (121C), however this system may be cured at 250F for one hour and a post cure of 350F for one hour. It can also be cured at 350°F for 1 hour. If properties over 200ºF are required you must Postcure to 350ºF. The times of the cure cycle are the actual part temperature for the designated time, not mold or oven temperature. The prepreg may be cured using either standard heat-up methods or by in-hot, out-hot press applications. A pressure of 30 psi is recommended, however pressures of 10 to 50 psi may be used.
