Super Glue in the Ultimate Test 😳🔥 Which One is the COOLEST?! | Mattin

Mattin starts the experiment by selecting six common instant glues from different brands: Loctite, UHU, Pattex Instant Glue Ultra Gel, Gorilla Super Glue, Bison Instant Glue, and a very cheap no-name glue from the hardware store. To create comparable conditions, he applies each glue sample in identical amounts onto two perfectly smooth aluminum plates, presses them together with exactly the same force, and lets them cure for exactly 24 hours. During this waiting period, he explains the chemical fundamentals of cyanoacrylate, why moisture plays a role in the curing process, and what to watch for in storage to prevent the glue from spoiling prematurely.

After curing, he builds an improvised test stand: the glued plates are clamped into a tensile testing machine that digitally measures the tensile force. In each run, Mattin increases the load in ten-kilogram increments until the bond breaks. The no-name bond fails at just 20 kg, which Mattin documents with a slow-motion camera. UHU holds up to 30 kg before the adhesive surface detaches. Pattex Ultra Gel achieves 40 kg and displays a tough, elastic failure. Gorilla Glue and Bison provide a neck-and-neck race: both hold up to 50 kg, with Gorilla Glue giving way just slightly earlier. The surprising winner is Loctite, which breaks only at 60 kg, showing the strongest instant adhesion.

Next, Mattin demonstrates a practical test on wooden strips to see if the results are transferable to porous materials. Here, Pattex Ultra Gel excels thanks to its rubber-like filling capacity, while the no-name glue disappoints once again. Mattin points out that pure tensile values don't tell the whole story: temperature resistance, impact toughness, and gap-filling ability are also crucial, depending on the application.

In conclusion, he summarizes the key tips: surfaces must be free of grease and dust, a minimal glue layer is sufficient, and lightly sanding smooth metals can increase strength by up to 50%. He recommends storing glue in the refrigerator to extend its shelf life and warns against mixing super glue with baking powder, as the exothermic reaction can cause burns. His conclusion: for quick, high-strength metal-to-metal bonds, Loctite is the 'coolest' glue in the test, while Pattex Ultra Gel remains the most versatile choice for everyday repairs on wood and plastic
