Technical Details & Test Data
- Cure Cycles and Performances
- Recommended Cure Cycle:
1 st dwell at 75°C for 1h, at a ramp rate of 1°C/min under full vacuum
2 nd dwell at 120°C for 1h, at a ramp rate of 2-3°C/min under full vacuum
For optimum performance, it is recommended that the part is subject to a post cure of 150°C for 2 hours
Cure Initial Min Cure Tg 65°C (minimum) 16 hours 70°C 75°C 8 hours 80°C 85°C 4 hours 90°C 100°C 2 hours 105°C 120°C 1 hour 125°C 130°C (maximum) 45 minutes 135°C 150°C Post cure 2 hours 140°C Resulting panel thickness for OPS75 surface and PSB75 bulking after full consolidation, around 1.5-1.7mm. For additional thickness and stiffness if required, additional PSB75 bulk or OPS75 surface plies may be used.
Other cure cycles and additional reinforcements are available on request.
Use of perforated release film is recommended.
- 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 3.0°C per minute during initial cure.
Ramp rates must not exceed 0.3°C per minute during post cure (free standing).
Safety & Health
- Health And Safety
This material contains epoxy resin which can cause allergic reactions with skin contact and must avoid repeated and prolonged skin contact.
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 3.0°C/min during initial cure and 0.3°C/min during post cure.

Storage & Handling
- 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.
