Storage & Handling
- Storage Conditions
- ARALDITE® CW 177 contains fillers, which tend to settle over time. Before partial use we recommend the resin be carefully stirred to re-homogenise it or to use each container as complete unit.
- The components have to be stored under dry conditions at 10 - 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 re-analysis. Partly emptied containers should be closed tightly immediately after use.
