Cyanoacrylate Adhesives

Cyanoacrylate Adhesives

Permabond still manufactures the original cyanoacrylate formulation Permabond 910 (previously Eastman 910). The name 910, comes from counting to 10 as the inventor determined that the product sets between 9 and 10 seconds.

Since that original methyl cyanoacrylate formulation Permabond has expanded the versatility of its cyanoacrylate product line to include a tremendous number of formulations, each with unique characteristics that overcomes specific design and manufacturing challenges.  Including more methyl cyanoacrylates, and also, ethyl cyanoacrylates, alkoxy alkyl cyanoacrylates, and more.

Permabond cyanoacrylates are ideal for bonding materials such as metal, rubber, composite, plastic, silicone and many more substrates. New formulations continue to eliminate design challenges encountered by engineers trying to bond difficult plastics such as polypropylene, polyethylene, PTFE, and other polyolefins. Permabond’s high performance industrial cyanoacrylate adhesives that are available provide very fast set times, a range of viscosity choices as well as non-blooming / low odor formulations, and products with very high temperature resistance.

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.
