I used to seal stuff for some marine applications using a tube of "Amazing goop" in its "marine" version. It's not very viscous so I am not so sure how it will work for you considering the size of the ibuttons. You'll find that in DIY places like "ace hardware".
I've also managed to watertight stuff using some PVC pipe cement. It's more viscous and when it is dried, the cement is highly thin and resistant. Some stores which sell electronic component also ave some spray to isolate any circuitboard from moisture and water.
