- Health and Safety
The following precautions must be taken when using epoxy resin prepregs:; 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.

- Low Shrinkage
- Temperature Resistance
- Storage and Out Life
This material should be kept frozen at -18°C. 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.. Important Note: If bags are opened before fully cured, condensation may form on the material. Cyanate ester prepregs may react with moisture, which can affect the curing reaction and cause voidage. Great care must be taken to avoid contact with water. Thoroughly dry all tooling and fixtures before commencing lay-up.
- Typical Applications
High service temperature – Aerospace / Motorsport
- Recommended Cure Cycle
Recommended Initial cure:; 70°C for 22h, at a ramp rate of 0.5°C/min; Recommended Post cure:; 1 st dwell at 250°C for 2h, at a ramp rate of 0.3°C/min o 2 nd dwell at 300°C for 2h, at a ramp rate of 0.3°C/min (where required for high Tg); *may produce charring and reduce service life; Important Note:; It is recommended that post curing is carried out immediately after initial cure. This will remove the risk of performance degradation due to moisture absorbance.; 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).
