what is the expiration date?

Bought mine 3/18/2021. Exp date says, 3/04/2022. So, about a year from buy date, depending on how often supply is refreshed.

Why this product has so short expiration date (1 year)? I have other Loctite threadlockers (in tubes), no expiration date on them.

The date is mainly for.manufacturing companies, but it shouldn't affect home users.

Is the bottle supposed to be sealed? What happens after the expiration date? It is only 6 months. Can it dry or won't work after 6 months?

I have been using Loctite both blue and red for many years. I never had any problems using it when it's old. I didn't even realize that they put an expiration date on the bottle.

Excellent Threadlocker for Reliable Holds

Loctite Threadlocker 242 in the 50mL blue bottle is fantastic! It applies easily without mess, sets quickly, and provides a strong, vibration-resistant bond on bolts and screws. I’ve used it on automotive parts and machinery, and it holds up perfectly without loosening over time. The blue formula is removable if needed, which is a big plus for maintenance. Highly recommend for anyone needing dependable thread locking—great value and performance!
