Cyanoacrylate glue, also commonly known as Krazy Glue or super glue, is an instant adhesive that creates exceptionally strong polymer bonds between a variety of materials. Unlike other adhesives, cyanoacrylate (CA) glue does not require additional treatments to cure and harden to the surface of a material. Exposure to moisture or humidity in the air is sufficient to activate the bond between the active ingredient, ethyl cyanoacrylate, and the material. Anionic polymerization triggered by exposure to water molecules allows CA glue to create polymer chains that can bond to a range of materials, from wood and metal to ceramic, leather, and plastic. 

Cyanoacrylate is the umbrella term for instant adhesives (also known as superglue or power glue). You may recognize popular cyanoacrylate brand names such as PermaBond, Krazy Glue, or Gorilla Glue. Cyanoacrylate is incredibly versatile and has been used for almost 70 years in product assembly throughout a variety of industries, including automotive, medical device manufacturing, electronics, construction, and consumer products. While one may think they’re aware of all the uses of this powerful adhesive, there are some “unconventional” applications of cyanoacrylates we thought would be interesting to share with you. 

At Toagosei America, we formulate cyanoacrylates – also known as instant adhesives, industrial-strength Krazy Glue – and have expanded our portfolio to include Aronix® and Aron Oxetane® UV-curable resin. 

Cyanoacrylates—also known as CA glue, ethyl cyanoacrylates, super glues, instant adhesives, or Krazy Glues—are adhesives made from cyanoacrylate esters (most commonly ethyl). These adhesives are primarily characterized by their fast cure time when moisture is present. Once solidified, they form strong and rigid bonds between two substrates pressed firmly together.

Though you may not be familiar with the term cyanoacrylate adhesive, you're probably familiar with the product itself. Commonly called super glue, instant glue, power glue, or by the brand names such as Krazy Glue, cyanoacrylate adhesive is critical to the assembly of goods for a variety of applications across industries. These glues are heat resistant, dry quickly, and will bond almost any material with another, making them ideal for a wide range of applications. 

Throughout the years, innovations in construction material and manufacturing processes have led to medical-grade adhesives replacing the use of traditional fastening systems in medical device assemblies. When properly applied, adhesives present significant advantages over other mechanical fastening methods.

The strength behind industrial super glue is often a topic of conversation with our customers.  So we thought we would create this post to provide an overview in an attempt to cover this topic.  As we mentioned in a prior post, keep in mind, not all super glues are created equal.  In fact, there are varying types of super glues (also known as cyanoacrylates), that are intended for various type of applications.

When choosing an adhesive for an industrial or consumer assembly application, it is important to identify and understand the differences between the types available. Adhesive manufacturers produce a variety of adhesives, each of which exhibits distinct chemical characteristics and provides different advantages and disadvantages depending on the use case.

We thought we would take time out from talking all about cyanoacrylates to deliver a more light-hearted message, for fun of course.  Even if you are actively involved in the adhesives industry, our guess is that you likely aren’t familiar with the comprehensive history of adhesives. We don’t want to go too deep into the complete details of how one of the greatest inventions known to man came to be, so we thought we’d break it down into a whole bunch of fun, interesting and lesser-known facts about adhesives.
