Cyanoacrylate: What You Didn't Know About Super Glue
Do you use super glue without really knowing what's inside? Cyanoacrylate is the star molecule behind all so-called “instant” glues. But at Colle21, we do much more than just copy others. Here's what makes our formula unique—and why it truly sticks!
🧠 What Exactly Is Cyanoacrylate?
Cyanoacrylate is a type of resin that hardens very quickly upon contact with moisture and under pressure. This chemical reaction is what enables the near-instant bond between two surfaces.
In short:
✅ It doesn’t dry in open air—it activates only between two compressed surfaces
✅ It works on a wide range of materials (plastic, metal, wood, ceramic, leather…)
✅ A tiny drop is enough for a strong hold
🚫 Why Doesn’t Colle21 Dry in the Bottle?
Unlike cheap glues that harden as soon as they’re opened, Colle21 is anaerobic:
➡️ It only dries when compressed between two surfaces.
The result:
🧴 Long shelf life (over 1 year if properly sealed)
🚫 No waste
💧 A fluid texture that stays easy to apply
🔍 SEO Keywords: glue that doesn’t dry in the bottle, professional cyanoacrylate glue, long-lasting glue
