- 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 250°F (121°C), however this system may be cured at 250°F for one hour and a post cure of 350°F for one hour. 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.
