WebJun 2, 2024 · Super glue is known to have massive tensile strength, and this is where it excels. On the other hand, super glue is notoriously weak in terms of shearing strength. Let’s take a look at the experiment that Loctite did back in 2009. Loctite attempted and succeeded in lifting a 5-ton truck with only 9 drops of its regular super glue adhesive. WebMost cyanoacrylates are one-part systems that cure rapidly at room temperature and provide excellent shear and tensile strength.
