- 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.
- Material Features
- Excellent Toughness
- Improved Flexibility
- Low Shrinkage
- 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.
- Typical Applications
- General purpose – Visual
- Recommended Cure Cycle
Recommended Initial cure: 60°C for 14h, at a ramp rate of 1.0°C/min; Recommended Post cure: 120°C for 1h, at a ramp rate of 1.0°C/min; 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).
