UV Curing Guidelines*

Humiseal Vivid Cure™ UV9118T Black adhesive has been formulated to allow flexibility in the curing process. Humiseal Vivid Cure™ UV9118T Black can be cured using full-spectrum mercury vapor light systems as well as 365nm and 395nm LED systems. The table below details minimum dosage values required to properly crosslink Humiseal Vivid Cure™ UV9118T Black.

Note: Adhesive thickness range of 700 – 750 microns was used during the development of the minimum required dosage values recommended below. If a different adhesive thickness is used, process adjustments may be required.

Storage & Handling

Humiseal Vivid Cure™ UV9118T Black 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 the 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 Cure™ UV9118T Black should be avoided.
