Accidents happen. No matter how careful you are, every now and then that favorite coffee mug slips from your grasp or that precious ceramic keepsake gets knocked over. Don’t despair! Common cracks and breaks are precisely what super glue is designed for. Super glues offer an effective way of mending various materials, while being super easy to handle.
Even though sealed, moisture will eventually seep in and ruin the mixture, causing it to “self-glue.” You can extend the shelf life to the outer limit of 12 months if you store unopened containers in a cool, dark space, between 50 and 70 degrees Fahrenheit to keep condensation from forming.
How strong is super glue?
Super glue creates an incredibly strong adhesive bond. Because of cyanoacrylate glue’s unique properties, the bond formed is nearly unbreakable. It’s so powerful, Loctite cyanoacrylate adhesive broke the Guinness World Record by lifting a car weighing more than 5 tons with just 9 drops of adhesive.
Chris Marshall: There are a lot of dynamics that impact a good glue bond, so quantifying an expected lifespan of a glue’s particular application would be tough. Think about it: sunlight, moisture, wood movement, chemical breakdown, original surface preparation and the wear and tear of the object’s use over time all will impact durability of glue bonds. The toughest all-around glue is probably slow-setting marine-grade epoxy. It holds tenaciously, fills gaps, is pretty much impervious to water and withstands wood movement well. Boat builders swear by it. If you want extreme durability, I’d probably go that route straightaway over CA glue, regardless of the application.
Kathy Hoelscher: Cyanoacrylate, or super glue, can be permanent; however, it can degrade with exposure to moisture or some solvents like acetone. If the project is stored in ambient conditions, it should be a permanent fix. If the project is stored outside or in an area with temperature or humidity swings, bonds can degrade.
Cross-linking PVA’s like Gorilla Wood Glue are formulated to be more water-resistant than those that do not cross-link during cure and so can withstand more weathering. However, most aren’t waterproof, so — again — the lifetime of the bonds is going to highly depend on how they are stored.
As for PVA glue bonds, they could theoretically withstand 30 years of exposure, depending on how the project is stored and the stability of the wood. If, over time, the wood dries out, warps or undergoes swelling and drying cycles with temperature and humidity swings, then this can put stress on the glue bonds and degrade bond integrity.
I would like to know about the permanence of cyanoacrylate glue. One can expect 30 years or more from good quality PVAs (polyvinyl acetates). What do the cyanoacrylate glues offer for durability? -Raul

FAQ
Does super glue get weaker over time?
How many years will super glue last?
Does superglue degrade?
Does super glue become brittle?
How long does super glue last?
In general, super glue has a shelf life of about one to two years when stored properly in a cool and dry place. However, once opened, its lifespan can be significantly shorter. Once exposed to air, super glue can start to harden and become less effective over time. The longevity of super glue also depends on the surfaces it is applied to.
How long does super glue take to dry?
Now, here’s a pro tip: patience is key when it comes to curing super glue. Though it may appear dry on the surface within seconds, it is best to let it sit undisturbed for at least 24 hours to reach its maximum strength. During this time, a chemical reaction occurs between the adhesive and moisture in the air, ensuring a durable bond.
What factors affect the longevity of super glue?
Environmental factors such as temperature and humidity can also impact the longevity of super glue. Extreme temperatures, both hot and cold, can affect the bonding strength and durability of the glue. Similarly, high humidity levels can slow down the curing process of super glue and reduce its overall effectiveness.
What are the advantages of using super glue?
Resistance: Super Glue can withstand extreme temperatures (-40°F to 180°F), making it suitable for both indoor and outdoor use. Quick curing: It forms bonds within seconds, saving time and increasing productivity. Lack of flexibility: Super Glue bonds may become brittle when subjected to frequent bending or twisting.
