General instructions for preparing liquid resin systems
- Long pot life is desirable in the processing of any casting/ impregnation resin system. Mix all of the components together very thoroughly at room temperature or slightly above and under vacuum. Proper mixing will result in:
- better flow properties and reduced tendency to shrinkage
- lower internal stresses and therefore improved mechanical properties on object
- improved partial discharge behavior in high voltage applications.
- For the mixing of medium- to high viscous casting/ impregnation resin systems and for mixing at lower temperatures, we recommend special thin film degassing mixers that may produce additional self-heating of 10-15 K as a result of friction. For low viscous casting resin systems, conventional anchor mixers are usually sufficient.
- Mixing time can vary from 0.5 to 3 hours, depending on mixing temperature, quantity, mixing equipment and the particular application. The required vacuum is 0.5 to 5 mbar. The vapor pressure of the individual components should be taken into account. Machine parts have to be heated up to impregnation temperatures. Viscosity of the bath can be adjusted in the range between 25-50°C. After having finished the impregnation process re-cooling of bath in separate vessels is recommended.

Storage & Handling
- Storage Conditions
The components have to be stored under dry conditions CY 30010 CH at 2-40°C and HY 30011 BD at 4-28°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. Due to its high purity Araldite CY 30010 CH tends to crystallize. It can be liquified to its original state by heating to 70°C and stirring.
