Description

Airtech CEP prepregs are based on a unique cyanate / epoxy resin chemistry. This chemistry allows greater flexibility in curing. Airtech CEP prepregs cure at a lower temperature than competing BMI or benzoxazine prepregs.

CEP-G3 is a light weight tooling prepreg with a high glass transition temperature (Tg).

CEP-G12 is a heavy weight tooling prepreg with a high glass transition temperature (Tg).

Benefits

• High resin Tg means high service temperature and longer tool life.
• Low initial cure temperature option in comparison to other high temperature prepregs.
• Low moisture absorption of cure laminate reduces risk of porosity in parts.

Cure Instructions

Notes

• Temperature measurements should be obtained with thermocouples, properly placed for accurate
temperature readings. Program controller should follow lagging thermocouple for cure and post cure.
• Do not apply solvent to the mould surface prior to post cure.
• To avoid condensation, allow prepreg from freezer to warm to room temperature before using.
