Epoxy Vs Super Glue

Since times immemorial, humans have sought to hold different kinds of materials together. Be it wood, fabrics, or even metal, there are multiple methods available for joining objects together. Of the many methods available, two of the most popular ones that require a level of precision are using epoxy and super glue. This article seeks to explore the distinct characteristics of both epoxy vs super glue, and evaluate when to use them and for what purpose. We will discuss the strengths and weaknesses of each, the time products need for setting, the relevant costs associated, and the level of ease in using them. Hopefully, this article will take you from a state of perplexity to one of sufficiency when it comes to selecting the perfect adhesive for your projects.

What is Epoxy?

Epoxy is a powerful adhesive that can be used to bond a wide range of materials, from metallic and plastic surfaces to fabric and wood. It’s been in use for decades in home improvement projects and professional manufacturing practices for its strength and versatility. It’s two-part epoxy, also referred to as two-part resin, is composed of part A and part B, which is mixed together after application and begins to cure immediately. It can be used for permanent bonding, casting, filling holes or cracks and creating durable surfaces. It’s resistant to water, oils, and solvents, making it an excellent choice for a variety of applications.

What is Two-Part Epoxy?

Two-part epoxy is a versatile form of epoxy that is made from two separate components: a resin and a hardener. When the two components are combined and allowed to react, a strong bond is formed that will keep your project parts together.

Two-part epoxy is extremely strong and can be used to join a variety of materials, including metal, plastic, glass, and wood. Additionally, the bond created is waterproof, heat-resistant, and will not shrink or expand over time. This makes two-part epoxy a great choice for projects that need to withstand different environmental elements.

Using two-part epoxy is simple. All you need to do is mix the epoxy base and hardener in the ratios specified by the manufacturer. Once the two parts are combined, it takes approximately 30 minutes for the epoxy to cure. After the curing time is up, you can use the epoxy to bond your project pieces together as needed. It’s important to note that two-part epoxy has to be applied while it is still wet, so you want to make sure that you are ready to apply it when you mix the resin and hardener.

Two-part epoxy is one of the most reliable forms of glue to use on projects due to the strength of the bond it creates and its waterproof and heat-resistant properties. When used correctly, two-part epoxy can ensure your project will stay together for many years.

What Types of Projects Is Epoxy Used For?

Epoxy is great for a variety of projects that require a stronger bond than traditional glue. It is often used to bond dissimilar materials, such as metal, wood, glass, ceramic, and plastic together. Epoxy is also ideal for filling large gaps and repairing cracks.

Epoxy can be used to:

  • Create jewelry and decorations
  • Repair tile, stone, and ceramic surfaces
  • Reconstruct broken items
  • Form durable seals
  • Create a watertight seal on items
  • Seal seams and bonds between different materials
  • Fiberglass repair
  • Replacing missing and broken parts
  • Furniture repair
  • Bonding metals, wood, and plastic together

Epoxy is also a great choice for constructing molds and prototypes, and it is often used in robotics. It is also used to mount and assemble objects, such as signs and statues. In addition, epoxy is used in boat construction and repairs, automotive repairs, and electronic repairs.

The uses for epoxy seem to be virtually limitless, as it is also used to repair different types of art and to create sculptures, mosaics, and built-in furniture pieces.

What is Super Glue?

Super glue is a type of adhesive that quickly forms a strong bond between surfaces. It is a simple, convenient way to complete projects quickly and easily. Super glue is often used for crafts and DIY projects, in addition to repairs, such as fixing models, figurines, toys, and broken items. It is typically more affordable than epoxy, making it an accessible option for many applications.

What Types of Projects is Super Glue Used For?

Super glue, or cyanoacrylate, is an adhesive used for a wide range of projects, from basic repairs to more complicated projects. It cures quickly, so there is no waiting to begin a project. Here are some common uses for super glue:

  • Gluing plastics and ceramics
  • Making quick repairs on ceramic items
  • Bonding metals together
  • Gluing various nonporous items such as stone, glass, and rubber
  • Making temporary repairs to soft materials – rubber, foam, and fabric
  • Gluing and maintaining small items such as beads, jewellery, and crafting supplies
  • Making repairs to items such as toys and tools

Super glue can also be used for constructing models or for creating small sculptures. It sets quickly, so larger projects must usually be assembled in smaller sections.
Super glue can also be used to create intricate designs or molds, such as for making sculptures or cake decorations. It is usually used only for smaller items, as the bond may not hold for larger items.

Super glue is also widely used for sealing and waterproofing items, such as pipes and fixtures. It can help to create an air or watertight seal on pipes, but should not be used on items that come into direct contact with food or drink.

Which is Better – Epoxy or Super Glue?

Choosing between epoxy and super glue is a difficult decision, as both products have their own unique advantages and drawbacks depending on the project. In this section, we look at how these two adhesives compare – from their strength and durability to their cost and ease of use – to help you decide which is better for your project.

Strength and Durability

Epoxy and super glue are two popular adhesives used in a variety of projects. For some projects, one adhesive may be superior to the other in terms of strength and durability. When comparing epoxy and super glue, it is important to consider a range of factors, including strength and durability.

Epoxy is a two-part adhesive composed of resin and hardener, which when mixed produces a durable, strong bond. Depending on the type, the mixture can create a bond that is shatterproof, waterproof and heat-resistant. The bond created by epoxy is typically stronger than that created by super glue.

Super glue, also known as cyanoacrylate, is a one-part adhesive that creates strong, fast-acting bonds. Super glue is also often used for projects where it is necessary to make a waterproof or shatterproof bond, however the bond created is usually weaker than that of epoxy.

When comparing the strength and durability of the two adhesives, it is apparent that epoxy usually outperforms super glue. For projects in which a strong and long-lasting bond is required, such as for gluing metal to metal, epoxy is often the better option. Super glue is generally better for projects where a fast-acting bond is needed, such as repairing pottery, china and glassware.

Setting Time

Setting time can be a key factor when deciding between epoxy and super glue. Epoxies have a much longer curing time than super glues, ranging from 60 minutes to several hours, depending on the type of resin. This is because epoxies need to be mixed together to create a reaction that results in hardening. By contrast, super glue generally sets in just a few minutes. This makes super glue ideal for quick repairs that need to be done in a hurry. On the other hand, epoxies provide a much stronger bond and are better suited for heavier-duty jobs that require more time and attention.


Epoxy and super glue are both used for a variety of projects, but when it comes to cost, the two become a bit more complicated. Generally, super glue is the cheaper of the two, since very little is needed and single-use tubes can be purchased relatively inexpensively. On the other hand, epoxy requires two parts to be mixed in order to be effective. This can become quite expensive if a large project calls for a lot of epoxy, as it must be purchased in larger quantities. Additionally, epoxy requires a certain environment in order to properly cure, which can require additional materials, such as a UV light curing chamber, which can further increase costs. Both products are fairly inexpensive, however, and are good options for projects that are within a strict budget.

Ease of Use

When it comes to ease of use, epoxy and super glue have immense differences. Super glue is typically a one-part adhesive, making it very easy to use and only requires the user to place it on the desired surface and then press the two items together. On the other hand, epoxy is often a two-part adhesive, requiring the user to mix a resin and hardener together and then apply it to the desired surface. This process can present a challenge since a user must mix the two parts evenly while simultaneously timing the process. Additionally, prepared epoxy adhesives also require the user to knead the epoxy prior to application, leading to even more steps in the application process.

In terms of environmental conditions, epoxy will typically require very specific temperature, humidity, and air pressure conditions to create the strongest bond. If these conditions are not met, the epoxy may fail to make a strong bond. In comparison, super glue doesn’t usually have such stringent requirements and has a much higher tolerance for a variety of environmental conditions.

In summary, when looking at the usability of epoxy and super glue, super glue is the clear winner. Super glue is a ‘one-and-done’ process, requiring minimal effort once the material is applied. On the other hand, epoxy is a two-step process requiring precise mixing ratios for optimal performance. Furthermore, epoxy is sensitive to environmental conditions, making its application significantly more difficult and challenging than super glue.
