Vacuum infusion- 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.

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
