10 Fascinating Facts About Adhesives You Probably Didn’t Know

Here are 10 incredible facts about adhesive glue that highlights just how fascinating this sticky subject really is!

1. Adhesive Have Ancient Origins

The oldest known adhesive glue, discovered in central Italy, dates back 200,000 years. Early humans used birch-bark tar to bond stone tools, proving that adhesives have been vital to innovation for millennia.

2. Spiders Produce Natural Glue

Certain spider species create glue-like droplets on their webs to catch prey more effectively. Researchers are studying this natural innovation to develop biomimetic adhesive glue — a concept Supex closely follows in our R&D approach.

 3. Gecko Feet Inspire Reusable Adhesive

Geckos can walk on smooth walls thanks to millions of microscopic hairs on their feet. This unique adaptation inspired the creation of dry adhesives — residue-free and reusable — a field that’s influencing future bonding tech.

4. Post-it Notes Came from a Glue Failure

The now-iconic Post-it Note was born from a failed attempt at creating a super-strong glue. Instead, it resulted in a repositionable adhesive — now a staple in homes and offices.

5. Tooth Enamel is Nature’s Super Glue

The proteins bonding dentin and enamel in human teeth are among the strongest natural adhesives. Supex.in draws inspiration from nature like this to support advances in biocompatible glues and precision bonding.

6. Mussels Stick Underwater

Mussels secrete a special protein-based glue that works underwater. This discovery is paving the way for medical adhesives and surgical sealants, areas that continue to inspire innovation at Supex.

7. Some Adhesives Strengthen with Moisture

Some modern hydrogel adhesives actually get stronger when exposed to water — ideal for internal medical applications where traditional adhesives might fail.

8. Hot Glue Has Heavy-Duty Applications

Hot glue is more than just a craft tool. It’s a crucial component in automotive manufacturing, packaging, and construction. At Supex, we provide industrial-grade hot-melt adhesive glue for high-demand sectors.

9. NASA / DRDO Relies on Advanced Adhesives

In space, adhesives must withstand extreme temperatures and vacuum conditions. NASA uses epoxy resins and polyimides — and at Supex, we admire this level of innovation as we design high-performance bonding agents.

10. Some Glues Are Stronger Than Steel

Adhesives made with carbon nanotubes or cyanoacrylates can create bonds stronger than welded joints. This technology is part of the inspiration behind Supex’s commitment to offering metal glues and adhesive glue for extreme applications.
