What is Cyanoacrylate?
Simply put, cyanoacrylate is an acrylic monomer that cures to a ‘plastic’.
How Do Cyanoacrylate Adhesives Work?
Permabond’s cyanoacrylate adhesives (also called instant adhesives or super glue) cure by reacting to very small amounts of moisture on the surface of the components being bonded. That’s it – no ovens, no mixing, no specialty curing equipment – they simply cure from the residual moisture naturally occurring on the surface of the components. Permabond recognizes that in applications such as wire tacking and tamper-proofing the adhesive is not compressed between two surfaces. For this type of application where the adhesive is exposed, activators are available. Simply spray the activator on the exposed cyanoacrylate to instantly cure it. Cyanoacrylate activators can also be used on very dry or acidic parts or to facilitate cure prior to wicking into porous substrates.
