RECOMMENDED OUT OF AUTOCLAVE PROCEDURE
- Apply maximum vacuum pressure from the start of the curing cycle, using one vacuum valve per sqm of surface area. Maintain a high vacuum level, typically around 980 mbar.
- Place monitoring thermocouples on the surface to control curing cycle, in areas with the highest thermal mass or slowest heating rate.
- Increase the temperature at a controlled rate of 1 °C/min from room temperature to 80 °C.
- Maintain the cure temperature at 80 °C.
- Start the curing cycle dwell once the slowest monitoring thermocouple reaches 80 °C.
- Hold the dwell for 300 minutes.
- After curing, cool at a controlled rate of 1–2 °C/min to either room temperature or 30 °C, whichever is higher.
For recommended curing cycles and process descriptions of other methods, please refer to the Technical Data Sheet.
