Unusual Applications of Cyanoacrylates

Cyanoacrylates are quick-acting adhesives, often known as super glues or power glues. They are a strong and convenient product used for many purposes in industry and at home. Let’s look at what cyanoacrylates are, the advantages they offer, and some of the more unusual applications super glues are used for.

What Are Cyanoacrylates?

Cyanoacrylates are a group of adhesives called acryls that bond materials instantly in the presence of moisture. Because they are fast to work with and create high-strength bonds, they are often used in assembly tasks in automotive, medical device manufacturing, electronics, construction, and consumer products.

Cyanoacrylates set quickly without the use of clamps, so objects or assemblies can be handled within seconds. Bonds have high tensile strength and are effective with stiff or rigid materials. Once cured, cyanoacrylates have low ductility and can be brittle, making them vulnerable to impact loads. They are less stable when used with wood or at joints.

Advantages of Cyanoacrylates

Cyanoacrylate super glues provide many advantages, including:

  • Ease of use: Cyanoacrylates are single-component adhesives, requiring no mixing to activate the chemical bonding process. They are simple and non-messy to apply.
  • Fast cure time: The polymerization process is quick in the presence of moisture, so there is no need to clamp or secure components during cure time.
  • High bond strength: Long and strong polymer chain bonds are created as the glue cures. Some formulations can reach strengths of up to 20 megapascals.
  • Versatility: Cyanoacrylates are effective at bonding similar and dissimilar materials including wood, ceramics, elastomers, plastics, and metals.
  • Low Toxicity: Cyanoacrylates have relatively low toxicity compared to other adhesives.

Unusual Applications of Cyanoacrylate & Super Glue

Fossil & Mineral Repair

For years, fossils and minerals that broke or were already broken as they were excavated and prepared for analysis had to be thrown away. Then, scientists discovered that the viscosity and instant bonding qualities of super glue were ideal for salvaging these specimens. Cyanoacrylate doesn’t shrink and remains clear as it dries, making it perfect for use with minerals or jewels.

Crime Scene Investigations

A common procedure in crime scenes is collecting fingerprints, but did you know that cyanoacrylate is the adhesive used to collect them? Cyanoacrylates will adhere to the moisture that is deposited by the skin and turn the fingerprints white.

Repairs to Sunglasses, Shoes, Boots, and Straps

One of the handiest uses of cyanoacrylate glue is for small household repairs. You can extend the life of household items with just a small bead of adhesive.

Finger Protections for Guitarists

Guitarists can protect their fingers from cuts or blisters while playing by using super glue. Once the adhesive is applied to the tips of the fingers and allowed to dry, it creates a thin but tough layer that protects the skin from the abrasive guitar strings. Then, to remove the cyanoacrylate from the skin, they can apply one of the methods we mention here.

Underwater Bonding

The initial contact of cyanoacrylate with liquid creates a plastic outer shell, but the interior remains liquid for a short time. When you are ready to bond the items, you use a little force to break the outer shell, revealing the viable adhesive.

Finishing Wood Pens

This adhesive forms a hard, acrylic coating over the wood, protecting it from the ink. The cyanoacrylate glue is also very thin, allowing it to flow smoothly over the surface and dry to a high-gloss finish.

3D Printing Infiltration

3D finished components can remain powdery and granulated unless they are coated. Cyanoacrylates seal the porosity and create a solid, hard surface. Qualities like an ultra-fast cure, good penetration, brilliant color, and a matte or glossy texture make these adhesives ideal for 3D printing infiltration.

Tying Fishing Knots

Strong knots in fishing lines can be made simple with super glue. Place a bead of adhesive on the line where you tied it and drop it into the water for a much stronger bond that equates to a double or triple knot.

Most DIY Projects

The availability, ease of use, and low cost make cyanoacrylates ideal for almost any DIY project!

Medical & Veterinary Cyanoacrylate Uses

Surgical cyanoacrylate is used for suture replacements and various other applications in medicine. Additionally, absorbable grades of cyanoacrylate are being used to facilitate advancements in medical technology. Within the veterinary industry, butyl cyanoacrylate is commonly used to close surgical wounds.

What is the Best Super Glue for Bonding Rubber and Thermoplastic Elastomers?

Selecting the proper adhesive for a rubber bonding application demands a consideration of the processing and performance characteristics of the adhesive as well as the substrate material you will be bonding together. Depending on the application , you may need to adhere rubber to different substrates ranging from plastic to metal which might be flexible to hard, or even other rubber materials — each one presenting unique adhesion challenges.


How Strong Is Super Glue & Baking Soda?

Cyanoacrylate, commonly known as super glue, is the fastest-drying adhesive available on the commercial market. Valued for its high bonding strength and quick curing speed, cyanoacrylate is incorporated into everything from automotive manufacturing to furniture repair. Sometimes, even the exceptional speed with which cyanoacrylate cures isn’t fast enough. Whether you’re doing a tricky job that needs a quick adhesive bond or you’re just in a hurry, you can get your adhesive to cure even faster using baking soda.  


Super Glue Accelerators: Key Considerations & How to Apply Them

Super glue accelerators are an effective tool for making super glue applications more convenient and simpler with predictable and repeatable performance results. The primary function of an accelerator (also referred to as cyanoacrylate setters, kicker, boost, blast) is to facilitate extremely fast setting (curing) and bond times, however, it can be utilized to “build” or “mound” a surface to fill gaps and create a “fillet”, improve bonding on porous surfaces like wood, ceramic or foam rubber and used to help mitigate blooming or frosting on your finished assembled item.Aron Alpha Super Glue Accelerators


Why Should I Use Super Glue for Rubber Bonding?

Automotive rubber part production - rubber assembly

Rubber has many applications across a wide range of industries—from tires on cars and roofs on buildings to tubes in industrial equipment. In many of these situations, the rubber must be bonded to another piece of rubber, another kind of rubber, or another type of substrate (e.g., metal, wood, or plastic) to create a usable product. Forming an effective bonding necessitates the proper selection and application of an adhesive. The wrong type and method could result in a weak bond (or no bond) or damage the substrates. 


How to Get Super Glue (Cyanoacrylate) Off Your Hands

Super glue is an incredible tool for household repairs, hobbies, and more, but it can get messy—and getting it on your hands is pretty common. It can feel alarming to have your fingers stuck together or stuck to another object, but you don’t need to worry, because there are several ways to remove it. Don’t wait for it to dry and then try to peel it off. The bond is strong, and you may end up damaging your skin.


All About Cyanoacrylate Prototype Testing Methods

prototype-testingCyanoacrylates—commonly referred to as super glue or Krazy Glue—are fast-drying adhesive compounds. They create instant, high-strength bonds between various materials when exposed to moisture, including (but not limited to) metal, plastic, wood, ceramic, and rubber. These characteristics make them ideal for use in many industrial and commercial assembly applications, ranging from aerospace and automotive components to consumer appliances and musical instruments. However, before they are approved for distribution and use, they must be fully tested to verify that they provide the desired performance in the intended application.
