- Health and Safety
Overalls must be worn.; Impervious gloves must be worn.; Curing schedule is meant to be as a guide only and is subject to local conditions.; To avoid exotherm, particular care must be taken with thick laminates.; Ramp rates must not exceed 1.0°C/min during initial cure and 0.3°C/min during post cure.
- Material Features
- High Durability
- Low Shrinkage
- Temperature Resistance
- Storage and Out Life
This material should be stored at ambient temperatures in a cool, dry place. It must be kept sealed in a polythene bag which must not be opened until ready for use.
- Typical Applications
- High temperature aerospace tooling
- Recommended Cure Cycle
Recommended cure cycle 2 hours at 160°C followed by 2 hours at 180°C under 6 bar autoclave pressure. If required for Tg, a free standing postcure of 2 hours at 200°C can be carried out.; Curing Schedule is meant to be a guide only and is subject to local conditions.; To avoid exotherm particular care must be taken with thick laminates. Ramp rates must not exceed 1.0°C per minute during initial cure. Ramp rates must not exceed 0.3°C per minute during post cure (free standing)
