Prepreg tools- Processing Instructions
The temperature of material and processing should be between 18 and 25° C. The mixing of resin and hardener should be made intensively and if possible without any bubbles at room temperature. We recommend a post curing with a temperature rise of about 10°C/hour. Difficult geometries should be supported during the curing cycle. Afterwards the part should be cooled down at about 20°C/hour.

Technical Details & Test Data
- In General
Through step-by-step curing a high heat resistance will be reached. Cool down slowly to room temperature!
Postcuring in following steps:- 4 - 6 h bei 40° C
- 4 - 6 h bei 60° C
- 4 - 6 h bei 100° C
- 4 - 6 h bei 150° C
By additional postcuring of 4 hrs. at 160 °C-180°C Tg of about 200 °C will be reached.
We recommend to perform the complete postcuring on the master model , at least the first one should be made this way.

Storage & Handling
- Storing
At appropriate storage 18-25°C. Occuring crystallization due to disadvantageous storage conditions can be made return by warming up the material at approx. 60° C for some hours. Opened containers should be closed immediately after use and be protected against moisture. This material should be used up as soon as possible. Shelf life is indicated on the labels
