Hi Barb, E6000 is a silicon
E6000 is a silicon glue and, as such, cures with the help of moisture.
Apply the glue, “wiggle” the pieces to make sure the glue is in contact with both surfaces and immediately pull them apart. Allow to sit for 3 – 5 minutes and then put it back together and don’t even look at it for 24 hours.
Pulling it apart briefly povides the interior of the glue with accesst to the moisture in the air so that the glue cures more thoroughly. Not looking at it for 24 hours ensures that sligh movements don’t break the bond while it is still fragile.
We do this on countless night lights without issue.
