For large part:                   1 hour at 100 °C + 1 hour at 120 °C
                                          Demold to get free-standing parts
                                          Post cure: 2 hours at 180 °C
For small or medium part: 5 minutes at 150 °C or 20 minutes at 120 °C
                                          Demold to get free-standing parts
                                          Post cure: 2 hours at 180 °C
For pultrusion:                   10 meters per hour

Depending on the application process, the required application and its economical, the curing cycle can be optimized to fit the required properties.
