  1. How to Bond Materials

    Leave a Comment

    At first glance, bonding two surfaces may seem straightforward. However, the choice of adhesive is critical, as it must be formulated to work with the substrates and meet performance requirements. Failure to select the appropriate adhesive can result in an unreliable connection, potentially leading to structural failure. Let’s discuss what adhesive bonding is, how cyanoacrylate adhesives work, and how materials can be bonded with them.

    What is Adhesive Bonding?

    Adhesive bonding involves joining two surfaces together to form a seamless bond. The bond is achieved by applying glue, epoxy, or other plastic adhesives to one or both surfaces. In some cases, a piece of adhesive tape with a two-sided coating can be placed between surfaces to bond them. The bond forms by solvent evaporation, by a curing process with applied heat or pressure, or simply by curing over a period of time.

    Glues and adhesives form bonds of varying strengths. New and advanced self-curing glues have been developed that can create bonds as strong as, or stronger than, the materials they join. High-strength glues and adhesives are a common choice in many manufacturing, industrial, and household uses as a result. 

    Depending on the formulation, some adhesives and glues must be remixed prior to application to distribute ingredients. Others, such as two-part epoxies, must not be mixed until they are ready to be used. Some glues must be cured by applying heat or UV radiation, while others cure in the open air over a period of time. Our focus here will be cyanoacrylate glues, which do not require mixing, set quickly, and cure by atmospheric moisture (humidity) and latent moisture on the bonding substrate surface.    This is called an anionic bond or anionic polymerization causing the cyanoacrylate monomer to transition to a polymer bonding materials together.

    How Do Cyanoacrylate Adhesives Work?

    Cyanoacrylate, often referred to as an instant adhesive, CA glue, or super glue, is a liquid acryl monomer that achieves a fixture time in seconds. Over a period of hours, the glue cures completely for a high-strength, permanent bond.

    When placed between two surfaces, cyanoacrylate reacts instantly, forming polymer chain bonds as soon as it is exposed to residual moisture on the substrate surfaces. As a single-part adhesive, it does not require mixing and there is no need for heat or UV light to cure it. 

    In some applications in which the adhesive is exposed instead of being sandwiched between two surfaces, curing can be delayed. In these cases, a liquid activator may be sprayed on the glue to help it harden. These activators are also used in applications where one or both of the surfaces to be bonded is very dry, acidic, or porous. 

    Bonding Materials with Cyanoacrylate 

    Many materials can be bonded successfully with cyanoacrylate adhesive including ceramic, rubber, elastomers, textiles, metal, wood, and plastic. All-purpose, standard formula cyanoacrylates work well in many situations; however, they can also be formulated to enhance characteristics for specialized applications. Examples include:

    • Impact resistance
    • Thermal resistance
    • Peel resistance
    • Rigid or flexible curing
    • Water resistance
    • Low odor
    • Low bloom (i.e., spreading)
    • Specific substrates (e.g., soft/flexible, metal, plated material, porous material)
    • Ultra-fast set time
    • Extra clear when cured
    • Thixotropic, no-run formula

    Some materials are more challenging to bond. These may include very dry or acidic substrates; polyolefin, acetal, and fluoropolymers; or low surface energy plastics such as polypropylene and polyethylene. Surface treatment primers and adhesive accelerators are available to prepare them and improve adhesive performance.

  2. Curing Speed of Cyanoacrylate

    Leave a Comment

    Cyanoacrylate adhesive, also called “super glue,” is a strong, fast-drying glue used in industrial, commercial, and household settings. This versatile adhesive is easy to work with, but due to its short open time and permanent adhesion, it’s important to understand how it works, its cure time, and how to prepare bonding surfaces for the best results. Read on to learn more!

    What is Cyanoacrylate?

    Cyanoacrylate adhesive is a liquid acryl monomer that cures or hardens in the presence of moisture. There is no mixing required, and residual moisture is usually sufficient to initiate curing, though some applications require small amounts of water or liquid activator. As it dries, polymer chains form and create a strong bond without supplemental UV radiation or heat for full curing.

    There are several types of cyanoacrylate, including modified cyanoacrylates designed for less-reactive conditions, modified curing and fixture times, and longer shelf life. It is used in many household, medical, and industrial settings on materials including:

    • Wood
    • Metal
    • Plastic
    • Rubber
    • Elastomers
    • Paper
    • Leather
    • Fabric
    • Ceramics

    It’s important to exercise caution when applying cyanoacrylate to new materials. Some applications result in high exothermic (heat-releasing) reactions, especially when used in large amounts. For the same reason, cotton or wool gloves are not recommended when handling cyanoacrylate. Disposable nitrile gloves are best for protection against cyanoacrylates getting on worker’s hands.

    Curing Speed of Cyanoacrylate

    How long does cyanoacrylate take to cure? While most adhesives cure after a heating or evaporation process, cyanoacrylate fixes rapidly on contact with moisture. Even a small amount of humidity starts the curing process.

    This contributes to cyanoacrylate’s incredibly short fixture time. Total cyanoacrylate cure time depends on several factors:

    • Surface/material type
    • The amount of moisture/humidity present
    • Type of cyanoacrylate

    There are even faster forms of cyanoacrylate than store-bought superglues, such as surface-insensitive varieties. Toughened types and hybrid cyanoacrylate/epoxies have slower cure times.  

    Fixture Time vs. Cure Time

    How does cyanoacrylate cure so quickly? Technically, it is the fixture time that is very fast, often between 5 and 90 seconds. This is the amount of time until the glued assembly can be carefully handled. Full curing time, however, is when the bonding process is permanent and complete. Cyanoacrylate cure time is anywhere from 8 to 24 hours depending on the materials being bonded and the adhesive formulation used.

    The Super Glue brand once demonstrated cyanoacrylate’s immense tensile strength by lifting a car shortly after application. Even more impressive, though, is the fact that this was only its fixture strength and the full cyanoacrylate cure time results in even stronger bonds.
    Super glues are known for their high tensile strength, even at fixture time. Some famous examples have been illustrated in advertisements over the years, including vehicles and even people.

    Preparing Surfaces for Application Cyanoacrylate Adhesives

    How can bonding strength be maximized? Clean surfaces always bond best. Best practices include removing dust, oil, or grease with a detergent or cleaning solvent. Bonding primers (i.e., adhesion promoters), can also improve cyanoacrylate bonds by modifying surface energy. This promotes greater chemical reactivity between the adhesive and the surface, while also protecting the surface from contamination.

  3. Unusual Applications of Cyanoacrylates

    Leave a Comment

    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.

  4. What is Cyanoacrylate Glue?

    Leave a Comment

    Choosing the right adhesive for an application can be the difference between success and failure. When it comes to tiny components, small repairs, or applications calling for a strong bond that cures almost instantly, cyanoacrylate adhesives are hard to beat. 

    But what exactly are these powerful, convenient adhesives? Here we’ll look at how they work, their advantages, and a few of their many applications.

    What Is Cyanoacrylate Glue?

    Cyanoacrylate glue is a general term for a group of fast-curing, strong adhesives. Commonly called “super glue”, “crazy glue”, or CA glue, it is widely used in industrial and consumer applications to bond similar or dissimilar materials including plastics, ceramics, metals, and even skin.

    How Do Cyanoacrylate Adhesives Work?

    Cyanoacrylate adhesive is a liquid acryl monomer that cures or hardens in the presence of moisture. As it dries, the adhesive polymerizes, creating strong polymer chains that bond materials tightly. 

    The curing process is fast and because it is activated by moisture in the air or on the surface of the materials, it is simple to use in many settings. There is no need to mix multiple compounds, apply UV radiation or heat, or even clamp or secure parts during cure time. In many applications, nothing more than residual moisture is required to activate the adhesive; although, some dry or porous materials may need a small spray of water or activator liquid to start the process.

    Benefits of Cyanoacrylate Glue

    These key benefits make super glue a superior choice for many applications: 

    • Fast cure times: Glues with long cure times delay production and contribute to bottlenecks. Complex assemblies that need precise positioning require clamping or other methods to secure components until the adhesive is fully cured; however, cyanoacrylate glue activates and cures very quickly, so assemblies can be handled in seconds and production can continue.
    • Low-toxicity: Many industrial adhesives are toxic and release volatile organic compounds that are harmful to workers during production, and to consumers during post-production off-gassing. In comparison, cyanoacrylate glues have far lower levels of toxicity.
    • Simplicity: In most circumstances, super glue activates automatically due to exposure to moisture in the air or on materials. This makes it easy to use with no mixing or specialty tools. 
    • Strength: Cyanoacrylate glue forms extremely strong bonds between similar and dissimilar surfaces. It is also long-lasting and will not weaken if exposed to moisture. However, it’s important to note that cured CA glue has low ductility and may be vulnerable to impact loads.
    • Versatility: Unlike most high-performance adhesives, cyanoacrylate glues are effective with almost any type of material including metal, ceramics, plastic, wood, and textiles.  

    Applications: What is CA Glue Used For?

    Hobbyists, designers, and manufacturers of all sizes use cyanoacrylate glue to build complex assemblies and bind disparate components together. While it has uses in almost any setting, three common applications are aerospace, DIY, and medical use cases. 

    Aerospace Applications

    CA adhesives are often specified for aircraft interior components because it is strong and lightweight. They can also be used to repair minor damage to aircraft parts after the manufacturing process.

    DIY Applications

    Because it is simple to use and dries fast, super glue is a popular choice for crafting and repairs at home. It is especially convenient for bonding small pieces where only a tiny amount of adhesive is needed.

    Medical Applications

    Cyanoacrylate glue can be used in medical device and equipment assemblies where precision application is needed. Certain formulations can also be used to close wounds or small cuts on humans and animals.
