Just me, but I would use
silicone the adhesive caulk, rather than silicon like in microchips.
One or two 1 mm dots (the size of pin heads) of white glue is usually plenty to hold the nut in place. String tension does the rest. You might need a little more adhesive than normal since the string tension will be removed when folded up for travel.
And remember that we try to avoid silicone in polishes and anything that might touch the finish, because it will make future refinish work difficult or impossible. Future finish work is unlikely on a CF guitar, but still is conceivable.
