How long does threadlocker 242 take to dry?
Typically, threadlockers achieve ‘fixture strength’ in 20 minutes and fully cure in 24 hours. Fixture strength means it’s OK to put your assembly back in service, but a full cure is when you’re getting the full holding power of the threadlocker. Dirt, grease, and oil residue are all enemies of threadlockers.
How does Loctite 242 cure?
