Storage & Handling
- Storage
Humiseal Vivid CureTM UV 7041 should be stored between 8°C - 28°C in tightly closed, light-blocking containers, away from direct sunlight. Keep from freezing. Allow material to equilibrate to process area temperature for 24 hours before use. Please refer to product labeling for shelf-life information. While the material can be heated to facilitate degassing prior to use, this operation should be conducted only on the amount of adhesive to be immediately used. Multiple heating cycles of the bulk container or elevated temperature storage of Humiseal Vivid CureTM UV 7041 should be avoided. Consult SDS for full safety information.
