Processing Guidelines

For optimal results, mix all components thoroughly at room temperature or slightly above under vacuum. Intensive wetting of the filler is crucial for achieving superior flow properties, reduced shrinkage, lower internal stresses, and improved partial discharge behavior in high voltage applications.

Storage & Handling

Store components under dry conditions at 5-25°C in tightly sealed original containers. Shelf life corresponds to the expiry date stated on the label. Partly emptied containers should be closed tightly immediately after use.
