- Product End Uses
- System Preparation
Filament Winding
- To get good fiber wetting and reproducible building parts a temperature of 35-45°C is recommended for the impregnation bath. The mandrel temperature should be 60-120°C during winding. The gelling shall take place on the rotating mandrel at 90-120°C
Pultrusion
- To guarantee a good wetting of the fibers, the viscosity shall not exceed 2000 mPa.s. The temperature of the impregnation bath, has to be adapted correspondingly. Under these circumstances a pot life of least 90 min is achievable.
- These can also be influenced or adapted by the amount of the accelerator. It is advised to add about 2 pbw of DY 062 on 100 pbw of LY 3572.
- The accelerator is always to be added to the hardener.

Storage & Handling
- Storage Conditions
- The components have to be stored under dry conditions at 18-25°C, in tightly sealed original containers.
- Under these conditions, the shelf life will correspond to the expiry date stated on the label. After this date, the product may be processed only following reanalysis.
- Partly emptied containers should be closed tightly immediately after use.
