Technical Details & Test Data
- Cure Cycles and Performances
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)
Safety & Health
