Storage & Handling
- Storage Conditions
Araldite® 8680 Resin / Hardener 8685 polyurethane adhesive should be stored in a dry place, in their original, sealed container at temperatures between +2°C and +40°C (+36°F and 104°F). Under these storage conditions, the shelf life is 1 year. The product should not be exposed to direct sunlight. If stored below 60°F, the adhesive should be brought to 60°F - 77°F and conditioned at this temperature for some time prior to use.
