Anaerobic sealers cure when:

Anaerobic sealers cure when there is no oxygen present because their polymerization relies on free-radical chemistry that is inhibited by oxygen. In an oxygen-free environment, the initiators generate radicals that propagate and harden the material. Oxygen, when present, scavenges those radicals and stops the chain reaction, preventing curing. Moisture or light aren’t required to trigger this type of cure, and they don’t promote it for anaerobic systems. So the condition that allows curing is the absence of oxygen.
