Why Glue Doesn’t Adhere to the Tube

Video why super glue doesn't stick to tube

It’s a question that may sound like the setup to a Jerry Seinfeld joke, but it’s actually quite intriguing. As creators of A Good Glue Stick, we feel it’s important to address why glue doesn’t stick to the tube. The simple answer is that it was intentionally designed that way. Consider this: a glue stick that adhered to the inside of the tube would be utterly useless. How could you possibly use it to bond two objects together? And, of course, it wouldn’t reflect well on us as a company if we sold such a flawed product.

The Science Behind It

The more detailed explanation lies in the formulation of glues, including the one we developed for our glue stick. These glues are designed to function when they are being used, rather than beforehand. Think about science fiction movies where space travelers emerge from hypersleep, only to face imminent danger from an alien threat. Glue operates in a similar manner, thanks to a component known as a solvent.

Understanding Solvents

A solvent is a substance that can dissolve a solute, resulting in a solution. For example, seawater is a solution consisting of various salts as solutes and water as the solvent. Imagine visiting the beach and filling a bottle with seawater. If you seal the bottle, the water cannot evaporate. However, if you remove the cap and expose the bottle to sunlight, the water will gradually evaporate, leaving behind the previously dissolved salt. Our glue stick functions in the same way. The container keeps the solvents and the glue, usually a polymer, locked together in a solution. Removing the cap allows the solvents to evaporate, waking up the polymers and enabling them to perform their task of bonding materials together. This process is known as mechanical adhesion, and it’s how our glue stick works its magic.

Safety Matters

Naturally, concerns arise about the safety of solvents. Rest assured, we wouldn’t be able to call our product A Good Glue Stick if it contained any hazardous substances. Our glue stick is CE certified and fully complies with health, safety, and environmental regulations. In fact, we’ve carried out a rigorous conformity assessment, established a comprehensive technical file, and signed a declaration that authorities can request at any time. So, to answer your question, the solvent we use is perfectly safe, as it is water-based.

The Marvel of Super Glue

Now, you might be wondering how super glue differs from regular glue. Most conventional glues harden as their solvents evaporate. For optimal adhesion, you often need to tightly press the bonded objects together and let the glue cure. Our glue operates in a similar fashion, but with an important distinction. Unlike many other stick glue products on the market, our glue can withstand significant pressure without leaving unsightly lumps behind.

Super glue, on the other hand, doesn’t rely on drying out. Instead, it undergoes a process called polymerization. This means that the individual liquid molecules gradually bond with each other until they solidify. Interestingly, this reaction is triggered by moisture in the air and occurs so rapidly that clamping the glued objects is unnecessary. Chemical adhesion is the term used to describe this process. It’s crucial to keep the container of super glue tightly sealed, as exposure to water vapor in the air can cause polymerization inside the bottle. Moreover, the high water content of your skin explains why even a small amount of super glue on one finger sticks immediately to another.
