APCM DA 4518
- Chemical Family
- Epoxy & Epoxy Derivatives
APCM DA 4518 is an epoxy prepreg designed for a temperature range of -67°F (-55°C) to 350°F (177°C), with a cure of 250°F (121°C) for one hour and or a cure of 350º F (177ºC) for 1 hour. This material needs to be post cure or cured to 350ºF to get the 350º properties.

- 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. This system may also be cure at 350°F for one hour the reason for the higher temperature is to have the higher operating temperature. The prepreg may be cured using either standard heat-up methods or by in-hot, outhot press applications. A pressure of 30 psi is recommended, however pressures of 10 to 50 psi may be used.
