Yes TBIII adds moisture to the wood when you use it. Which makes sense since it's water based.
I also know this is the case because as I said, I can start with wood that is completely stabilized to my apartment's climate, and after using TBIII to glue it up, I can weight it every day on a scale and see the bow losing mass very slowly. All evidence suggests that this is a result of moisture leaving the wood. Since everything was stabilized prior to gluing, this can only have come from the glue.
I view this as one of the primary drawbacks of using a water based adhesive.
Remember, DRY wood expertly tillered .... well if you tiller a bow right after TBIII dries, your wood has alot higher moisture content than you might think, and it WILL take more set than necessary.
I try to let mine dry for a few weeks after glue up. This doesn;t bother me too much because ususally I'll glue up a few at a time so while the first is drying, I'm gluing more bows, and by the time I'm done the first one is ready or close to ready.
