- Product Applications
- L-3790 may be applied by spray or gravure methods.
- Films must be dried completely before UV energy cure.
- UV irradiation is required to attain optimal film properties, but un-cured coating films are durable enough for handling prior to curing.

Technical Details & Test Data
- Curing
- L-3790 must be air-dried, or oven dried (temperature: 150 - 170° F; dwell time: 10 minutes) to remove water from the film prior to UV exposure.
- A photo-initiator must be incorporated into the coating formulation for effective curing.
- See starting point formulations for suggestions. Exposure guidelines: MPMA lamp - 300 watts/in² , 2.0 - 3.0 second dwell time.
