COMPOTOOL BoxPreg
COMPOTOOL BoxPreg is a high temperature Benzoxazine tooling prepreg for high production tooling. BoxPreg can be cured on the COMPOTOOL board at 225°C (435ºF) with a fast single cure cycle reducing demand on autoclave time. BoxPreg in combination with COMPOTOOL tooling boards significantly reduce tooling production time and costs. BoxPreg offers superior handling characteristics and 6 months working life at room temperature. High accuracy composite tooling can be produced in hours.
Key Features:
- 6 months out life at room temperature (≤25°C/75ºF).
- 24 months storage at -18°C (-40ºF).
- 260°C (500ºF) TG ideal for high production tooling.
- Low shrinkage for improved dimensional tolerance.
- Full cure on Compotool master model eliminating post cure off the master model distortion.
- Fast cure cycles.

Curing Information:
- Apply full vacuum at 0.97 Bar (14 Psi).
- Apply 6.2 Bar (90 Psi) autoclave pressure then vent to atmosphere when pressure exceeds 1 Bar (14.5 Psi).
- Ramp the laminate temperature up at a rate of 1~3ºC (4~5ºF) per minute until the lagging thermocouple reaches a temperature of 160 ±3ºC (320 ±37ºF).
- Dwell at 160 ±3ºC (320 ±5~ºF) for 60 minutes.
- Ramp the laminate temperature up at a rate of 1~3ºC (4~5ºF) per minute until the lagging thermocouple reaches a temperature of 225º ±3ºC (437º ±37ºF).
- Dwell at 225º ±3ºC (437º ±5ºF) for 3 hours.
- Cool to below 90ºC (194ºF) at a rate of 3ºC (5ºF) per minute before dumping pressure and removing from the autoclave.
For alternate cure cycles please contact your local Compotool representative.
Storage:
COMPOTOOL BoxPreg should be stored in protected area. Can be stored at room temperature for less than 6 months if the materials will be stored longer then keep below -18º (0ºF).
Supply:
Compotool BoxPreg is available in 1.27 meter (50 Inch) wide rolls or in 423 x 423mm (16.6 x 16.6 Inch) squares. For other custom sizes please contact your local Compotool representative.
