Am looking for a dispensable water soluble solder mask or peelable solder mask that can be dispensed and be run through a reflow oven with no swelling or degradation. Any leads on any materials or manufacturers to contact?

Did you try Techspray Wondermask W? It is water soluble and can probably be transferred from the bottle to an EFD type syringe for dispensing (we use the P and the PL that way). As far as if it will swell through the reflow, I don't know. We don't us
