Abstract: Ultraviolet (UV) curable coatings can be used to meet cost pressures and for improved coating performance when compared to other coating material. However, there are some unique process controls that need to be put in place to guaranty a well controlled process that does not require cleaning. This paper provides a review of a conformal coating process development for a coating using UV light to provide the cure mechanism.

A UV conformal coating line will usually consist of an In-feed conveyor, Coating applicator, Inspection station, UV Oven and an Out-feed conveyor. The UV oven and the coating applicator are the actual components in the line that require an understanding of the process mechanism and the effect that machine settings have on the process.
