Why doesn't glu become glue to the container it is contained by ?
Because the paucity of air in the container assuming you hang on to a tight lid on it (therefore keeping the glue from drying)
If you keep it sealed after it shouldn't dry and stick to the container, but if you leave it out for very long near the top off then eventually it will become glue to the container. It will if you leave the top off.
Most glue are air cured, and will dry up and set when exposed to air. In the container, near the top on, there is no source of air.
Answers: It can't oxidize.
