7. Oven Cure (see attached "Oven Cure SOP" for more details)
- Seeing as the cure cycle for System 3000 epoxy is around 12 hours, got four people to sign up for shifts (this requires planning in advance!)
- Positioned fin can
...
- vertically as shown and router the vacuum tube through a port hole on the right side of the oven. Positioning the fin can vertically is important so the fins don't splay and become misaligned.
- Followed the cure cycle for System 3000 High Temp epoxy. Note that the epoxy changes from clear to amber-colored after the cure is completed.
Need 2-3 people, not just one person, and do it during the day time! make a nice graph
...
- Increase from room temperature to 150F at a rate of no more than 2-5F per minute
- Hold at 150F for 3 hours
- Increase to 250F (no more than 2-5F per minute)
- Hold at 250F for 3 hours
- Increase to 300F (no more than 2-5 per minute)
- Hold at 300F for 3 hours
- Ramp down to 100F (no more than 2-5F per minute) --> decreasing temp takes a lot longer than increasing and lower temps are harder to control
- Do not shut down the oven and leave it to cool down
