What adhesive is this?

I have several ARTF foam models which are "glued" together with something that looks likes silicone bathroom sealant.  (ST Models, Eflite etc).   This adhesive seems to have the benefit of clean breaks when things like undercarriage fittings come adrift, with very little collateral damage to the surrounding foam.  eg. I have had two models in which the plastic undercarriage bearers came away cleanly as a result of a heavy landing but were very easily repaired.  I have made the repairs using hot glue, but I would prefer to use the silicone sealant (or whatever it is) if possible.  It seems quite "rubbery" compared to some bathroom sealants I have used.

 

Does anybody know what this stuff is and where I could source it?

I have used bathroom silicone sealant to glue servos into an e-flite Radian and it seems to work OK but I'm not sure I would rely on it for any joints which might be heavily stressed in flight. Next step up would probably be something like "No More Nails" but i'm not sure about its compatibility with foam.
