Both JB weld and Loctite epoxy weld are two-part epoxy made up of resin and hardener. Both of them are used as a convenient alternative to welding. But they also have some differences between them. In this article, I will try to compare jb weld vs. loctite. Hopefully, it will help you to understand the similarities and differences between these two products.

JB Weld vs. Loctite
Overview of JB Weld
The two-part epoxy adhesive JB weld is a special type of epoxy adhesive. It is made up of two parts: one is referred to as the resin, and the other is referred to as the hardener.
The combination of these two components forms a solid bond that is resistant to extreme temperatures as well as intense pressure and is highly durable. In order to apply these two parts, you will need to mix them together first.
JB Weld Pros and Cons
Pros
- Waterproof.
- Best for DIYers.
- Easy to use.
- Suitable for metal repairs.
- Durable and versatile.
Cons
- Hard to sand.

Overview of Loctite Epoxy Weld Bonding Compound
Loctite Epoxy Weld Bonding Compound contains two parts: epoxy resin and hardener. By mixing resin and hardener in equal volumes, a tough, rigid, high-strength bond is formed.
The Loctite Epoxy Weld is a convenient alternative to welding. This adhesive can be used to repair, fill, and rebuild all metal and common surfaces.
As soon as it is fully cured, it can be easily sanded, drilled, machined, or painted. Besides being resistant to water, diesel fuel, gasoline, antifreeze, hydraulic fluid, motor oil, and transmission fluids, it does not shrink.
Loctite Epoxy Weld Bonding Compound Pros and Cons
Pros
- Impact resistance is high.
- Resistant to water.
- It does not shrink.
- Water resistant.
Cons
- Little bit expensive.

Differences Between JB Weld and Loctite Epoxy Weld
| JB Weld | Loctite Epoxy Weld |
| Material: Polymer | Material: Epoxy resin / Amine hardener |
| Full Cure Time: 15-24 Hours | Full Cure Time: 24 Hours |
| Tensile Strength: 5020 PSI | Shear Strength up to 3000 PSI |
| Cure Color: Dark Grey | Cure Color: Metallic Gray |
Which One Is The Best? JB Weld or Loctite Epoxy Weld?
Both JB weld and Loctite epoxy weld bonding compound works well for so many things like metal, wood, glass etc. But if you want a super strong bond between those materials, then JB Weld is the best without any doubts. It is also providing a tensile strength of 5020 PSI after curing, which is the highest available in the market.
On the other hand, Loctite epoxy weld has a shear strength of up to 3000 PSI only. As JB Weld provides a strong bond with the highest tensile strength, so you can use it without any doubt if you want your bond to last in high-pressure situations. It will last more pressure than any other epoxy weld available in the market.
In terms of curing time, JB Weld also takes less time than Loctite epoxy weld. JB weld fully cures in 15 to 24 hours. On the other hand, Loctite epoxy weld fully cures in 24 hours. So, clearly JB weld can be fully cured in less than one day and Loctite epoxy weld takes at least one day to fully cure.
In terms of price, JB weld is the best. It costs almost half of Loctite epoxy weld and also works better than Loctite in many situations.
In terms of curing color, it depends on you which color you prefer. After fully cured, JB weld becomes dark gray. And Loctite epoxy weld becomes metallic gray. So, it totally depends on you which color you prefer for your project.
You can use JB weld if you have no problem with darkish color or you prefer a darkish color. But if you don’t want a darkish color then you can use Loctite epoxy weld.

Is Loctite As Strong As A Weld?
A convenient and strong alternative to welding, it bonds most metals, including iron, steel, aluminum, brass, copper, and pewter. After curing, it resists heat, cold, oil, fuel, antifreeze and water.
How Long Will JB Weld Last?
If the caps are tightly secured between uses, JB Weld tubes will last up to 25 years once opened.
Is JB Weld As Strong As Steel?
The Original JB Weld creates a bond stronger than steel to repair multiple surfaces and is perfect for DIY household, automotive, marine and craft repairs.
Last Opinion
In almost all comparisons, JB weld becomes the ultimate winner. JB weld is the best for creating strong bonds, it takes less curing time and it is also less expensive too. But you can use Loctite if JB weld’s cure color is not preferred by you.
