As you probably already know, epoxies are very strong. Most are two-component adhesives that, when mixed, create a bond that is virtually unbreakable. Technicqll Very Strong Epoxy Adhesive Glue is a good example of this, as it has been called “liquid metal” because of its tight grip. Just like with any epoxy glue, before application, the surface you’re working with needs to be thoroughly cleaned and degreased to ensure the best possible bond and two components need to be mixed in equal proportions.

The epoxy can handle temperatures as low as -86 degrees Fahrenheit and as high as 158 degrees Fahrenheit. The adhesive works on alloys, cast iron, concrete, steel, brass, bronze, aluminum, and other metal types. It will even bond to plastic and stone so that it can aid in the completion of projects that involve multiple materials.

The bond is resistant to acids, oil, and gasoline. In other words, it is ideal for harsh environments.

The glue takes initially 90 minutes to set and fully cures in approximately three hours.

Pro tip: use a blowdryer to greatly reduce the curing time!
Once dry, epoxy leaves a metallic gray trace. The bond is extraordinarily strong in our experience.

Pros
  • Behaves like “liquid metal” due to its strength
  • Will hold together multiple materials, including many types of metals
  • Cures very fast
  • Resistant to cold and hot temperatures
  • Resistant to oils and acids
Cons
  • Surfaces require extensive preparation

When you see Elmer’s name, you probably think about the glue you used in school. Well, Elmer’s does much more than creating white paste and glue sticks used in art classes; the company creates professional-strength glue that is waterproof. It’s Advanced ProBond stands up to all types of weather and can bond metal, unlike its little brothers and sisters hanging out in art boxes around the world.

Also, unlike school glue, this glue is runnier. It’s important to be prepared for the glue to come out fast, otherwise, it’s easy to squeeze out too much.

Fortunately, E7502 Advanced ProBond can be quickly cleaned up with water. It’s non-toxic, despite its ability to bond metal, concrete, stone, wood, and many other material types. When the glue dries, it is translucent and can be painted over really easily.

Overall, this is a simple glue that gets the job done. It’s nice that a name we know from our school days has entered the world of multi-surface professional adhesives.

3M is known for its products, including the Scotch-Weld name. This is a two-part adhesive, but it mixes while being dispensed from the dual-nozzle bottle, which eliminates the need to manually mix the components. This alone saves time and ensures the mix is prepared properly.

However, this is a glue that is best dispensed in small quantities, so it’s going to take more glue for large projects.

Nonetheless, this epoxy is effective for joining, attaching, and even sealing. The bond is permanent and holds up well against impact and vibration because it expands and contracts with temperature changes. If applied at room temperature, the glued object or objects can already be handled in about 20 minutes.

This glue will work if you need to glue together items made of multiple materials. Its wide range of applications includes automotive, electrical, construction, and general industrial. Once applied, you have five minutes to make adjustments. The epoxy completely cures in 48 hours.

All in all, this epoxy works well for construction projects because of its ability to bond metal to metal and metal to dissimilar surfaces. It’s strong and reaches handling strength within 20 minutes.

Pros
  • Versatile and flexible
  • Bonds metal to dissimilar surfaces
  • Mixes as both compounds are dispensed from the bottle
  • Reaches handling strength in 20 minutes
Cons
  • Ideal for smaller projects, although more glue can be used for larger projects

Best Glue for Metal Buyer’s Guide

It’s believed that metal glues could replace soldering and welding in some applications. This is because the technology implemented in today’s metal glues and epoxies enables joining two metal objects or metal objects to other surfaces quickly, safely and efficiently. The bonds are tight and are becoming increasingly more resistant to temperature and harsh environmental changes.

How is this even possible?

First, two-part mix and no-mix acrylics, polyurethanes, and two-part epoxies have a lot to do with it. The adhesion strength and fast curing times of modern metal glues are achieved thanks to great advances in the understanding of the chemistry behind the polymerization processes and finetuning of components. When two components are mixed, short molecules of the liquids begin to form longer chains making the liquid viscous and sticky. During the curing process, these chains interlink forming a rigid lattice. The choice of components affects the number and configuration of these links, which results in either brittle strength or flexible resilience of the cured material.
Polymerization of single component adhesives, such as urethane, requires moisture on the surface or in the atmosphere to make the bond. During the curing process, carbon dioxide is released. However, an environment that is too moist can cause foaming. That’s why such glue may say it’s best to not use it in humid environments.

Metal to Metal Glue

While metal-on-metal gluing has come a long way with these technologies, new technologies have emerged.
Think about how hard it is to rub the bristles of two brushes together. In fact, you may not be able to move them at all because they interlace. On the molecular level, the bonding of new glues uses this kind of bristle interlacing. In this case, the role of the bristles is performed by “nanorods.”
Nanorods can’t be seen with the naked eye, but if you place the glue on two surfaces and press them together, the nanorods will connect and allow the metal to stick to metal. This is like soldering without heat and hazards. A nanorod bond can withstand heat and reach bond strength of up to 1,500 psi, which is greater than some solders.

Choosing the Right Glue for Metal

Now that you know a little about the technology, the question is how you know which glue for metal is right for you and your project?

Bond Time

First, consider your workflow so you know how much time you have. Adhesives have different drying and cure times. If an adhesive takes three days to cure and you don’t have three days, you must find something that cures faster. However, you have to ensure a shorter cure time doesn’t come at the expense of the bond strength.

Waterproof? Sun Resistant?

Second, think about the environment your project will be exposed to. Will the temperatures get very high, such as under the hood of a car? Are you planning to use it in cold weather? Will the rain be an issue, resulting in the need for a waterproof adhesive? The answers to these questions will help you narrow down the options.

Bottle Size

Third, look at the size of the project. This will help you figure out how many bottles of glue you need which determines the cost. One rule of thumb, however, is to not sacrifice quality for cost. Quality is everything when it comes to glue for metal because a poor bond could compromise the result or even be dangerous.

What Else?

Fourth, consider the user-friendliness of the glue. There are some glues out there that aren’t convenient or easy to use at all, especially when it comes to manually mix two-component adhesives. Others have bottles that aren’t easy to operate with one hand, especially when lacking a good applicator.
It’s good to consider everything that’s important to you in a metal glue so that the finished product is durable and of good quality.

Conclusion

There was a time when there was no other option to bond two pieces of metal together but by soldering or welding, which made for a dangerous and not readily accessible method. And the option to bond metal to other objects simply wasn’t available. With the advance of glues for that have the tensile and shear strength of a weld or solder, we’ve stepped into a whole new era of creative and technical possibilities.
