We use Shin-Etsu KE-3421, it is a condensation/moisture cure, tack free after 5 minutes or so, full cure in about 48 hours.

Dean,
We use Dow Corning 1-2577 as our approved silicone and it has always worked well for us. It is about 20-30% toluene, so it is a VOC, but if memory serves, there are low VOC versions of 1-2577 out there. While it does have a relatively quick tack time, you may want to bake it a while to drive the cure reaction and improve adhesion.
