10 Main Types of Glue You Definitely Need to Know About

10 Main Types of Glue

Are you unclear about the many types of glue that exist and the numerous purposes for which each one may be put to use? If this is the case, you’ve come to the right spot, since we’re here to take a closer look at the ten most common varieties of glue available right now. Let’s get started and figure out which shade of blue is best for you!

10 main types of glue are commonly used. These include super glue, Krazy glue, crazy glue, gorilla glue, polyurethane glue, epoxy, contact cement, hot glue gun, all-purpose adhesive, and fabric adhesive. Each type of glue has its own unique properties and uses. Superglue is known for its strength and versatility. Krazy glue is specially formulated to bond with

Super Glue – One of the Best Types Of Glue

The sort of glue known as super glue is, without a doubt, among the most widely used and well-liked varieties now available. Cyanoacrylate is the primary component of super glue, which makes it a kind of cyanoacrylate adhesive, according to the technical definition of the term. One of the adhesives that bonds and hardens at an extremely rapid rate is known as super glue.

The Benefits and Their Numerous Applications

It is essential to keep in mind that superglue has remarkable tensile and shear strengths. One of the most powerful kinds of glue that can be purchased at this moment. This is certainly the case in terms of its capacity to support weight since superglue is capable of withstanding several thousand pounds per square inch. That is something that most people like. Superglue dries to a crystal clear finish.

It is important to keep in mind that superglue works best on porous or semi-porous materials such as metals, ceramics, wood, glass, leather, and other similar materials.

On slick plastic, Super Glue does not adhere very well at all.

In reality, superglue is not the best kind of glue to use for plastic at all, which is odd given the fact that when dried, superglue is more or less similar in appearance to the material.


The issue is that super glue doesn’t have a very high shear strength or impact resistance, which is the difficulty. Therefore, everything that involves impact or moving components will be adversely affected by this kind of construction.

One of the issues with Super Glue is that, despite its reputation for being resistant to high temperatures, it is not highly resistant to moisture, at least not after being exposed to it for an extended period of time. It’s true that superglue can tolerate brief exposure to water, but it won’t hold up to being submerged in it constantly. Furthermore, it is dissolvable by a variety of solvents, including acetone, which is well known as a nail polish remover.

The Process of Curing

It takes just a few seconds for super glue to begin to set, and it often doesn’t take more than a few minutes for it to fully cure. Please keep in mind that the curing process for super glue begins as soon as the glue is exposed to moisture.

Hot Glue

The next kind of adhesive that you have to be knowledgeable about is hot glue. For the avoidance of becoming too technical, hot glue comes in the shape of a solid plastic cylinder that can be easily manipulated.

Now, you can call it an adhesive if you want to, but in broad terms, it’s simply a small plastic cylinder. In other words, it’s not much more than that. To be more specific, hot glue is referred to as a hot melt adhesive or a thermoplastic adhesive, depending on the manufacturer.

Inside the hot glue gun is a mechanism that heats up this plastic cylinder as it moves through the device. This plastic or glue will then melt into a liquid state, at which point it may be applied to a surface; after a few minutes, it will begin to dry out and then re-harden into its original state.

To use a simple analogy, this may be seen as being comparable to removing ice cream from the freezer, allowing it to melt, and then replacing it in the freezer when it has been defrosted.

The Benefits and Their Numerous Applications

In the realm of arts and crafts, as well as in other contexts, such as when putting together boxes or gluing book spines together, this particular kind of glue is a common tool.

What’s handy is that hot glue dries and cures in a very short period of time.

Using hot glue that sets in a short amount of time is an option to consider if you are working on craft projects.

Now, one feature that sets hot glue apart from other adhesives is the fact that it can successfully join porous and non-porous surfaces, which is something that the vast majority of adhesives are unable to do.


You do need to be mindful of one thing, however, and that is the fact that hot glue is not heat resistant in any manner, shape, or form. The adhesive properties of hot glue include being waterproof, but not heat resistant, and it does not perform well when exposed to solvents. Not to mention the fact that it is fundamentally flawed and cannot withstand significant amounts of weight or pressure.

The Process of Curing

In most cases, it won’t take more than a couple of minutes for hot glue to start to set into a solid state once it has begun to cool down.

Spray Adhesives

Spray adhesive is a form of glue that is very intriguing to look into. This glue is delivered to the user in a pressurized aerosol can, as the name of the product indicates. Keep in mind that the phrase “spray adhesive” refers to a fairly broad form of adhesive, since the specific kind of glue that is housed inside a container might vary greatly from one can to the next. The most essential thing to keep in mind about this situation is that the term “spray adhesive” may be little more than a straightforward glue, while others can combine to create what are, in essence, layers of rubber.

The Benefits and Their Numerous Applications

Keep in mind that the kind of glue that may or may not be present within the can has an effect on the weather resistance, temperature resistance, waterproofing, and other properties of the can. He added that each of them may vary tremendously from one kind of spray to another. However, in most cases, this kind of glue is used for arts and crafts projects, such as collages, mounting puzzles, scrapbooking, and other similar endeavors. Other similar uses include these activities.


Let’s just get this out of the way: this material is terrible for both the health of people and the health of the ecosystem. You should by no means swallow or breathe in this kind of adhesive in any way, shape, or form. The aerosol itself, in addition to the many solvents necessary to maintain the liquid state of the adhesives within the container, is an extremely dangerous substance.

The Process of Curing

Remember that spray adhesives dry and cure when the solvents evaporate out of them, leaving behind just the adhesives themselves. This is something to keep in mind. Drying and curing may take anything from a few minutes to many hours or even an entire day, depending on the specific adhesive that is included therein.


Epoxy sometimes referred to as two-component epoxy, is widely considered to be the strongest form of glue currently available. You will get two components in this package, the first of which is a resin, and the second of which is the harder component, also known as the curing agent.

The Benefits and Their Numerous Applications

In spite of all of this, epoxy remains one of the most effective forms of glue available. This is due to its capacity to adhere to an extremely wide variety of substrates, including porous and non-porous materials. In addition to this, epoxy is completely impervious to water, it can withstand high temperatures without becoming molten, it is unaffected by most solvents, and it is capable of supporting a significant amount of weight. Epoxy is the strongest material available, pound for pound, as measured in terms of its capacity to withstand weight in terms of pounds per square inch. The epoxy may be used for a wide variety of purposes, ranging from simple repairs to more involved structural work.


Take note that in order to produce the greatest effects, the two components must be combined together in an equal proportion. The outcomes will not be satisfactory if the components are not combined in an even manner. Epoxy has a number of drawbacks, one of which is the fact that it may be somewhat dirty.

The Process of Curing

The hardener or curing agent is what initiates a chemical reaction that modifies the chemical structure of the molecules contained within the resin, which is what allows the resin to become hard when it is combined in equal parts with the resin. This reaction is what causes the resin to become hard. To put it another way, when the two are combined, they produce something that is, in essence, plastic.

Glue for yellowed wood

Be aware that when we refer to yellow wood glue, we are referring to a substance that is also known as yellow glue, carpenters glue, or aliphatic resin glue. This distinction is important to make. It is important not to confuse this with PVA glue or polyvinyl acetate glue, since they are not interchangeable.

The Benefits and Their Numerous Applications

PVA glue is the original and more fundamental form of wood glue, while aliphatic resin or wood glue is the more up-to-date variety of this product. It is vital to keep this distinction in mind when discussing this topic. This new sort of aliphatic resin is meant to be exceptionally temperature and water-resistant, in contrast to the traditional wood glue, which was not particularly resistant to high temperatures or to water.

Aliphatic resin wood glue has excellent bond strength and the capacity to connect porous pieces of wood to one another as well as to certain other materials. It is also suitable for use with porous pieces of wood and some other materials. Despite the fact that yellow wood glue may adhere to a variety of other materials in addition to wood, it is created specifically for wood. In order to successfully link it with other materials, those other materials must be porous.

The main takeaway from this is that yellow wood glue is resistant to heat and water and also has excellent bonding strength on top of all of those other qualities.


It is not possible for it to adhere to non-porous surfaces, and despite the fact that this form of glue is very resistant to water, it is not completely waterproof.

The Process of Curing

When it comes to drying and clamping, you can anticipate that this sort of glue will take around one hour to set and approximately twenty-four hours to fully cure. Also bear in mind that the moisture that is combined in with this form of glue is what causes it to harden. Yes, in order for this particular kind of glue to start the curing process, it has to be exposed to moisture.


PU glue or adhesive is a common name for this kind of adhesive or glue. Polyurethane glue is another kind of thermoplastic glue; it’s the kind that comprises reproductions of organic chain units connected to urethane links. The most important fact to remember about this sort of glue is that it’s constructed out of polymers.

The Benefits and Their Numerous Applications

In terms of overall bond strength, resistance to temperature, resistance to solvents, resistance to UV light, and resistance to water, it is one of the finest alternatives that are currently available. There is also the fact that the final glue’s degree of flexibility and stiffness might vary, depending on the various additives that are included in the particular adhesive.

The point is that this is one of the strongest and most flexible glues available, which is why it is often employed in applications that need a high degree of strength and flexibility. This is primarily an adhesive for use in construction, but it may serve a variety of other uses as well.


This kind of glue can only harden in the presence of moisture, it has a very limited shelf life, and it is difficult to remove after it has dried.

The Process of Curing

PU glue typically needs between 24 and 48 hours to properly cure, although this time frame may vary depending on the circumstances. Isocyanate and polyol are the two primary components that, when combined, produce a chemical reaction that, in turn, results in the formation of a solid adhesive. In order to get started, you are going to need some heat and some moisture. The greater the amount of moisture and heat present, the quicker and more effective the healing will be.

Clue for the White Craft

White craft glue is the form of glue that is often used for the majority of simple art projects, as suggested by the name of this type of glue. Elmer’s is a well-known brand that should be kept in mind if one is searching for the finest white craft glue available.

The Benefits and Their Numerous Applications

This kind of glue is made to adhere to somewhat porous materials, which are often used in the making of crafts. Materials such as fabric, felt, cardboard, and paper, among others. Be aware that white craft glue is water-based, which means that it is quite simple to clean up if any of it gets on your hands.

Additionally, even after it has dried completely, there are a number of solvents, even something as basic as water, that may be used to remove the dried white glue. The advantage of using this form of glue is that it is generally harmless, which is why it is appropriate for children to use in most circumstances. White craft glue, despite the fact that this is not always the case, often dries transparent and is typically extremely flexible.


This particular kind of glue is incapable of fusing materials that do not have pores in them. Furthermore, keep in mind that although white craft glue is ideal for bonding extremely lightweight, porous materials, it does not have a great deal of weight-bearing power on its own. White craft glue is not suitable for use in anything that must maintain its structural integrity.

The Process of Curing

You may anticipate that this form of glue will take around one hour to set and that it will cure within approximately twenty-four hours after it has been applied.

Adhesives for Fabrics

Fabric adhesive is the following kind of glue that one should be familiarized oneself with. Now, what has to be noted is that this is not really a kind of glue to be accurate, since there is a range of glues that may be used as fabric glue, and this is something that needs to be said before moving on. The term “fabric glue” refers to any kind of adhesive that is capable of fusing two pieces of fabric together, hence the meaning is rather broad.

PVA glue, which is also known as regular white polyvinyl acetate glue, is one of the types of glue that may be used as an adhesive for cloth. Both superglue and epoxy may be used to attach cloth together.

When shopping for a product that is branded as fabric glue, it is important to be sure that you examine what kind of adhesive is really included inside the product before making your purchase. This is significant because if you are dealing with fabric, it indicates that you may need to place the items in question in the washing machine at some point.

However, not all adhesives are able to withstand being washed in the washing machine. As the name of this product suggests, it was definitely developed expressly for the goal of fabric bonding, which might be for the purpose of producing or repairing garments, as well as for the purpose of arts and crafts. Obviously, the adhesive in issue is going to be the primary factor in determining both how quickly it heals and the nature of the process by which it does so.

Glue Sticks

In the world of arts and crafts, glue sticks are a staple item. It is not recommended to use this kind of glue for any project unless you are adhering two pieces of paper together, or maybe some paper to feel or a porous cloth. This glue may be simple to apply since it comes in a stick form; nevertheless, despite its convenience, it has almost minimal adhesive strength and offers no other advantages. It is not resistant to temperature, ultraviolet light, water, or solvents. This is non-toxic children’s glue, which is intended specifically for use with young children.

Adhesives that are Sensitive to Pressure

The pressure-sensitive adhesive is the tenth kind of glue that we are going to discuss in a brief manner. Dots or stripes of adhesive tape are the most common forms that they take. There is a possibility that either one or both sides of the tape or dots possess adhesive on them. In most cases, this is concealed by a covering of some type, such as a sheet of plasticized paper that does not adhere to the glue or cause it to dry out.

After the cover has been removed, the object must be pressed firmly against the surface in order for the glue to take hold. Once this has been done, the glue will stick. The precise mechanism through which pressure-sensitive adhesives function is much too complex to be explained in a few hundred words. However, the reality is that when pressure is applied, the glue adheres to the surface. Stickers for kids’ school supplies and post-it notes are two of the most typical applications of pressure-sensitive adhesives.

What is the name of the world’s most powerful adhesive?

At the moment, DELO industrial glue is the world’s strongest adhesive, according to the company. DELO is a German-made glue, and we all know that the Germans are known for producing high-quality items. People, you just need a very little amount of this glue—just three grams of it—to be able to lift a vehicle that weighs 17.5 tons. Keep in mind that they are measured in metric tons, not imperial tons! That is, without a doubt, an outstanding accomplishment in its own right.

How Big of a Market Is There for Glue?

In spite of the fact that it does not seem to be so at first glance, the business of glue is really rather substantial, with the United States alone dealing with more than 11 billion dollars worth of glue each year. It may come as a surprise to learn that DELO is the manufacturer of the world’s most costly glue, yet this is the case.

What Kinds of Things Did People Historically Put Glue-On?

To be more specific, the oldest documented mention of glue being used for anything dates back to Ancient Egypt, when the tombs of pharaohs were often sealed with glue. Even before that, there is evidence to show that humanoid hunters employed natural types of adhesive to affix arrowheads and spearheads to their respective shafts thousands of years ago.
