Storage & Handling

Storage Conditions

URALANE® 5773-A/B should be stored in a dry place, in the original sealed container at temperatures between 2°C and 40°C (36°F and 104°F). Under these storage conditions, and when supplied under Huntsman standard certification, the product has a shelf-life of 6 months from date of shipment (expiration date may differ based on customer specification). The product should not be exposed to direct sunlight. These products are moisture sensitive and are packaged under a blanket of dry nitrogen. After opening a container, re-blanket with dry nitrogen and then tightly reseal.
