Boatbuilding- Processing Instructions
Material and processing temperature between 18 - 25°C. Intensive mixing of resin and hardener at room temperature, if possible without any bubbles. Stir up thoroughly before use. Mixing ratio according to instructions to get a homogeneous consistency . To remove any brittleness and to get best possible mechanical and thermal properties after curing a postcuring of 12-16 hrs. at 80°C is necessary. At postcuring of 24 hrs. at 60°C you achieve temperature resistance of 78°C according to ISO 75 B and 90 % of mechanical properties. To avoid deformations, postcuring should be made in the mold or on an adequate supporting 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
