BAGGING PROCEDURE

Notes:
1. Debulk every four plies, or as needed, when laying up material
2. It is recommended that panels have a pre-cure vacuum hold depending on size: for small panels 1 hour, for medium
sized panels (>1ft2) for 3 hours, and for complex layups (ply drops, >2ft2) for 16+ hours.
3. The vacuum should be checked for leaks before beginning the cure cycle. The leak rate shall be less than 2.0 inches ofHg (7 kPa) over 5 minutes.
Please refer to the SDS for handling and disposal.

VACUUM (Hg)

TEMPERATURE (°F)

1. Apply full vacuum* to the part. Higher vacuum levels will yield better results.
2. Maintaining vacuum for at least three hours prior to beginning cure cycle is recommended for optimal part quality. This
promotes the extraction of trapped air and gases, producing a lower void content.
3. Ramp to 270 ± 10°F at 1-5°F/min (132 ± 5°C at 0.6-2.8°C/min) and hold for 120 minutes.
4. Cool temperature down to 130°F at max rate of 5°F/min (54°C at 2.8°C/min).

Recommended for thick laminates, to reduce the risk of interlaminar voids and exothermic reactions during cure.
1. Apply full vacuum*. For optimum results, keep the part under vacuum for 16+ hours before the oven cure.
2. Ramp to 200 ± 10°F at 1-5°F/min (88 ± 5°C at 0.6-2.8°C/min) and hold for 90 minutes.
3. Ramp to 270 ± 10°F at 1-5°F/min (132 ± 5°C at 0.6-2.8°C/min) and hold for 120 minutes.
4. Cool temperature down to 130°F at max rate of 5°F/min (54°C at 2.8°C/min).
