Vacuum casting
- System Preparation
- The filled ARALDITE resin component should be stirred and homogenized in the original containers before use.
- To facilitate stirring and removal, filled components are heated to 60-80°C in the container (e.g. overnight in an oven).
- To prepare the casting mix the resin should be homogenized in holding tank A at 65- 80°C under a vacuum of 1-5mbar, the hardener in holding tank B at 25-45°C and a vacuum of 1-5 mbar. The preparation time depends on the quantity and preparation parameters. A metering unit should be used to feed the ARALDITE resin and the ARADUR hardener to an impeller mixer.

Storage & Handling
- Storage Conditions
- Prefilled, liquid products always show small filler sedimentation.
- Before partial use we recommend to stir up carefully the components or to use each container as complete unity.
- Store the components in a dry place 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 after reanalysis.
- Partly emptied containers should be tightly closed immediately after use.
