Does Super Glue Last?
Super glue, also known scientifically as cyanoacrylate, is one of the strongest and most reliable adhesives available. While traditionally used for construction and repairs, this multipurpose adhesive is now often used to mend everything from shattered glassware to figurines and much more.
When properly used and sealed, super glue can last anywhere from four months to several years. However, the actual lifespan of a particular adhesive depends on several factors, including the surface it was applied to, the type of super glue used, and the environment it is in.
Some of the most important factors that could influence the durability of your super glue bond include temperature, moisture, and air exposure. If a sealed bond is exposed to too much humidity, the water can seep in and break down the glue, causing it to weaken. Likewise, some super glue formulas don’t hold up well in temperatures above 150°F. Heat and oxygen can also weaken and break down the core molecular structure of the adhesive, making it peel off or become brittle over time.
UV exposure is also a factor in the long-term durability of a super glue. If a bond has prolonged UV exposure, the UV light can break down the adhesive, causing it to become brittle and crack over time.
Of course, the type of super glue used can also have a big effect on how long it will last. Because there are so many types of adhesives on the market, it can be difficult to know which will provide the best level of longevity. Generally speaking, industrial-grade super glues are made with tougher ingredients and more chemical stabilizers, making them more durable in a variety of conditions than regular household super glues.
Ultimately, the longevity of a super glue bond depends largely on the conditions it’s exposed to, the type of adhesive used, and the surfaces being bonded together. If you’re looking for an adhesive with maximum longevity, it’s always best to talk to an expert about the products available and the conditions you’re working in.
