- 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.

- 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.
