While working with electric parts or circuits, the most common thing that crossed our mind- does glue conducts electricity? Although the soldering method is mostly used to join the electrical boards, not everybody can use a soldering machine. Instead, they go for glue as an adhesive material.
Different types of adhesives or glues are used in joining electric components. If you need conductivity, go for epoxy conductive glues. Or else, you can use the normal glues or glue guns!
So today, let’s find out about the conductivity of glues. Also, have a comparative discussion between using the soldering Method and glues in joining electrical components. So let’s begin…

Conductive Glues and Non-Conductive Glues
The glues that we use in our daily lives for crafting or other purposes are not electrically conductive. The reason being, they are a type of petroleum product. So these glues have no conductivity properties.
Not to mention, these glues work as an insulator. So the answer is simple-glues are not electrically conductive.
But you might ask, does hot glue conduct electricity? Well, whether the glue is in hot-liquid form or solid, its conductivity property matters the most. The hot glue that we use mostly is made from polyurethane. Polyurethane is a type of plastic that melts when heat is applied.
So is there any glue that conducts electricity? Yes, there are glues available that conduct electricity.
It is rare to find conductive glue that is used for daily activities. But there are a few types of glue designed to be an easy-to-use alternative to Soldering. So what type of glue conducts electricity? Well, there are many different types of conductive adhesives. Metals like Silver, copper, iron, or other types of conductive metal are used to substitute Soldering.
Despite being more conductive than ordinary adhesives, these conductive adhesives have several drawbacks. As you already know, wire glues have metals like iron or silver in them. But adding these metals takes away the adhesive properties from the glue. They become less adhesive, although they can conduct electricity!
Fast forward, does glue conduct electricity? Yes, a few types of glues have conductivity properties. But 90% of the glues act as an insulator.
Will it be a good choice to use glues where electric conductivity is needed? No. As said above, with the insertion of metals in glues, the adhesiveness of the glues drops. Although these conductive adhesives will help in thermal conductivity, the joints will not be strong enough to hold them for a lifetime.
Soldering vs. Glue
Undoubtedly a soldering gun is our go-to option when it comes to joining metallic components. Some of us even never imagined using glue instead of the soldering method. The reason is obvious. Soldering creates a strong bond compared to glues.
But for a Soldering iron, you need to have basic knowledge about it first. It requires technical skills to operate. So if you’re not a technical person or haven’t used a solder machine before, it can get difficult. So as an alternative, a glue gun does the work best.
Glue guns require no technical skills to use. You just have to give an electrical connection to the glue guns and push down the meted glues in the circuit board or anywhere you want. The electric supply melts the glue stick in the hot glue gun.
Although glue guns are easier to use, the glue takes a few minutes to set up. Moreover, it can also get messy while using glue to connect circuit boards. Not to mention, not all glue or glue sticks can conduct electricity.
Most of the glues are made from plastic residues or petroleum. They don’t have conductivity properties and cannot be used in high-frequency circuits. So if you’re thinking of using hot glue instead of solder, it’s necessary to know these facts before.
Although most of the glues don’t conduct electricity, some glues conduct electricity. These glues are specially made with 80% metallic properties. So you can use this kind of glue in place of Soldering!
Soldering Method to join Electric Components
Pros:
- Creates a strong bond.
- Quick connection.
- Great for conductivity.
- Less chance of coming off.
- A soldering iron is highly effective even for small or little joints.
- Time-efficient .
Cons:
- Requires technical knowledge.
- A soldering gun can be risky to use.
- Costly.
Using Glues to Join Electric Components
Pros:
- Glue guns are easy to use.
- Availability.
- Can be used to connect low power components.
- Cost-efficient.
Cons:
- Not conductive (except for a few).
- Cannot be used in high-frequency circuits or components with high power.
- Time-consuming.
Using glue Instead of Soldering: Is it a good choice?
So you’ve already known about both Soldering and glues for joining electric boards. It entirely depends upon your need whether Soldering would be perfect instead of glues. Both soldering and glues have got some positive sides and drawbacks.
If conductivity isn’t a concern, a two-part epoxy intended for metals, such as JB-Weld, is a preferable choice. It is more powerful than any conductive adhesive available.
An electrically conductive glue or wire glue may be a feasible alternative to soldering for electrical components when conductivity is crucial.
On the other hand, wire glue or metallic glue is appropriate for low-power tasks such as light switches and battery connectors. It is not appropriate for anything that requires mains power since it cannot tolerate the high voltage and may cause a potentially hazardous malfunction.
So if you’re thinking, can I use glue instead of solder? We hope you got your answer!

FAQs
1. Does Gorilla glue conduct electricity?
Ans: Gorilla Glues are made with different types of non-conductive epoxy materials like plastic and petroleum. So Gorilla glues possess no conductivity properties. Also, there is no metal particle filling present in it. It works as an adhesive agent and insulator!
2. Do liquid nails conduct electricity?
Ans: Liquid nails are one kind of adhesive like plastic glue. They’re mostly made from rubber which has 0.14 W/mK thermal conductivity. So, yes, liquid nails can conduct electricity. But they are not the best type of conductors!
3. Does gum conduct electricity?
Ans: In some gums, carbon nanotubes are present. Carbon nanotubes are known as electric carriers. As carbon nanotubes can conduct electricity, gums also can! That’s why they are also called metallic glues.
4. Does super glue conduct electricity?
Ans: generally, super glues are made from plastics or polyurethane. Super glues are, in fact, polymers, just like every other plastic material. Due to this, they are not electrically conductive. If you use them to connect electrical wires or boards, it can do this. But due to being insulators, current cannot pass through super glues.
5. Can I use glue on a circuit board?
Ans: You can use hot glues on hard components like resistors, solenoids, and ceramic capacitance. The reason is, epoxy resins are used to make insulators. So hot glues are allowed to be applied to them. Remember not to overuse hot wire glue in the sensitive components. Or else, the circuit boards can get messy and damaged
Conclusion:
Conducting glues can be a very good alternative to Soldering. Although regular glues are cheap and available, conductive glues are costly and hard to find. One of the reasons behind this is, conductive glues are new to the market, and only a handful of people are aware of these conductive glues.
It’s not as conductive as well as effective as Soldering. Also, it’s also more costly than Soldering. So does glue conducts electricity? Yes, they do. Should you use it instead of Soldering? No. In general, I’d advise against buying these glues. Instead, opt for an inexpensive soldering machine!
