Safety & Health
- Health And Safety
The following precautions must be taken when using PFA resin prepregs:
- Impervious gloves are recommended.
- To avoid exotherm, particular care must be taken with thick laminates.
- Ramp rates must not exceed 3.0°C/min during initial cure and 1.0°C/min during post cure.

Storage & Handling
- Storage and Out Life
This material should be kept frozen at -18°C for a maximum storage life. If kept refrigerated at 6°C storage life will be reduced to 2 months. It must be kept sealed in a polythene bag which must not be opened until fully thawed to room temperature. If the material is not fully used, then the material must be resealed in the polythene bag to prevent moisture absorption.
