Check RadTech conference proceeding in the past 7 yrs. Depend on A,B or C. AR, UR, or SR or etc. If it is not absorb, nothing. If it is UV cure, too fast cure may generate some initiator being cooked, change color, and start absorb at the wavelength that not designed to. The key is eliminate "all" the absorption sites in the intended use window (pay good chemist money and buy yourself a good night sleep. ask the bean counter stay away from the process :)

Subject: [TN] UV radiation and conformal coating
Good morning all,
Does anyone know of any papers on the effects of UV light on conformal
coating? Not talking the cosmic radiation hard space kind. I know it
would be wavelength and intensity specific. Got a question from one of
our engineers and I, of course, gave the very intelligent answer of "Beats
me". But I have this wonderful resourse called Technet...............
