What is cyanoacrylate superglue and why is Colle21 different from the rest?
🔬 What is cyanoacrylate glue?
Cyanoacrylate superglue, better known simply as super glue, is a powerful instant adhesive used to bond plastic, metal, ceramic, wood, rubber, glass, leather, and much more.
Its active ingredient is cyanoacrylate, a monomer that rapidly polymerizes upon contact with moisture in the air or on the surfaces being bonded, creating an extremely strong bond.
🧠 How does it work?
👉 Cyanoacrylate superglue requires no heat or prolonged pressure.
🧪 It reacts instantly to moisture and pressure between the two surfaces.
The result? Nearly instant adhesion and exceptional strength.
