I use 2 different materials and processes and used UV cure in a prior timeline:
Present:
If I have high volume, with SMT or through-hole, at least pre-wave on only a single side, I use Lackwerke Peters SD2950 series.  It costs a few pennies a PCB and the PCB Supplier puts it on.  Saves time and labor and has an excellent seal.  You will have to design a masking layer to go with the PCB files, but not a bad way to go.
If it is just general run of the mill, I use Wondermask 2211 (Pink, non-staining).  It is air dry and will also final cure over the pre-heaters.  Otherwise it is an hour (or 2) to air dry.
Prior:
For UV Masks, I used a benchtop dispenser and a UV-A curing station (10 seconds) although I could have probably dialed it back to 5 seconds as it set up pretty quick.  I tried a short UV tunnel (12 inches) right on the line, but did not remind the operator after the tunnel to flip the PCB over BEFORE they started putting parts in, so I cured offline after that mistake.  I used the Dymax 9-20515 (RED).
