If you’ve ever gone through any repairing work, you probably heard the name of JB weld. The international brand is well recognized for producing epoxy products.
In fact, the JB weld is the flagship product of the JB weld company which is a high-temperature epoxy adhesive that helps to bond materials together. It is used to create bonding between materials made of any combination of iron, steel, aluminum, wood, ceramic, glass, PVC, and many more.
So, what is JB weld and how strong is JB weld?
JB weld is a popular adhesive manufacturing company from the United States. The glues are extremely strong that they’re sometimes compared to provide as much strength as steel.
JB Weld Products Overview
The Original Cold Weld, a two-component epoxy system that was first introduced as a substitute to traditional torch welding. This J-B Weld has a tensile strength of 3960 PSI and sets to a hard bond overnight. It can withstand temperatures up to 550ºF when fully cured. It takes about 15-24 hours to cure completely.
Now, here I bring some of the JB weld products that are used for different purposes with their strength and cost.

How Was JB Weld Started?
JB weld was founded in 1969 by Sam Bonham and Mary Bonham. The Bonhams used to run a truck repairing shop. Sam once felt the requirement of repairing parts without welding. He started working on it with the assistance of a chemist from Texas A&M. They could formulate a “tougher than steel” epoxy and named as JB weld.
Today, the brand has more numerous products under its name and all of them are produced to make the repair work easier and long-lasting.
What Is JB Weld Made Of?
So, you are probably keen to know what materials are used to produce the adhesive that makes such strong bonds between materials. Well, not all bonds are exactly the same and there’re different types of glues to be used for different applications. You’ll find three major types of adhesive cure namely, evaporative, reactive, and chemical.
Evaporative adhesive cures are usually made of plant and animal tissues. The moisture of the glue slowly evaporates with time, leaving the adhesive to harden. Thus, the glue eventually builds a strong mechanical bond between two parts of the materials. The mechanical bond can be stronger than the substrate parts even, making the repaired parts stronger than before.
The reactive cure is a type of single-component adhesives that cure through chemical processes by reacting with air, moisture, and radiation. Reactive glues offer more strength than evaporative ones and made of a combination of natural and synthetic based resins.
Chemical or two-component adhesives are also known as “2K” or “epoxy”. JB weld is an epoxy that truly offers extreme strength compared to evaporative and reactive cures. The two components, when unmixed, have long shell lives.
However, when they’re mixed together, they quickly begin to solidify. Modern vehicles are structured using this type of adhesive. They are so strong that the metal itself may tear apart before it can be separated from the adhesives.
How To Use JB Weld?
Okay, let’s come to the point. To build a strong bond between two parts of the material, you first need to know how to use the JB weld adhesives. Most of the epoxy’s usage is pretty much similar. You need to follow few steps to apply these adhesives on any particular surface.
At first, you need to prepare the area of the surface where you want to apply the glue. Clean the dirt, grease, oil, paint, or loose debris from the place. You may use detergent for the best result. Then roughen the surface with file or coarse sandpaper to ensure the best repair.
Secondly, squeeze equal parts from each tube and mix them thoroughly.
Then, apply the adhesive in an even coat on the surface you intend to fix.
At last, you need to dry the coating for 15-24 hours. It takes 4-6 hours to handle the surface and more than 15 hours to use it like before.
Most epoxies and 2k adhesives are dependent on mixing ratios. Luckily, JB weld is easy to measure and mix. Most JB weld glues are available in a syringe with a double plunger to keep you stress-free as they guarantee to provide mixtures with perfect ratios every time. The putty sticks also offer easy measuring as you can simply slice off the exact amount you need.
How Strong Is JB Weld?
JB weld is designed to withstand even the harshest environments. Being a two-component or 2k epoxy system, it reacts chemically to create the strongest bond possible.
J-B Weld offers a tensile strength of 3960 PSI and sets to a hard bond within 15-24 hours. It can withstand temperatures up to 550ºF when fully cured. The weld is claimed to be tougher than steel.
All the JB epoxy products are based on the same chemistry, making them the best choice for any project you need to tackle.
- What is stronger than JB Weld?
Ans: Loctite Two-Part Professional Heavy-Duty Epoxy is closed to JB weld products in case of providing strength with about 3500 PSI of tensile strength. It also provides the quickest 5 minutes of curing time.
- Can you speed up JB Weld cure time?
Ans: Usually JB weld takes around more than 15 hours to be cured completely. However, if you apply heat the JB weld cure time can be increased. After certain hours, for example, 6-8 hours, if you place a heat lamp near to the weld, it may speed up the cure time.
What is JB weld and how strong is JB weld? If you searched for the answer to the questions, I believe I could make you understand how strong the adhesives are.
JB weld produces quite a lot of products for different automotive and household purposes. If you need to fix any of the broken parts, JB weld has you back. Being so strong and long-lasting, JB weld adhesives have become one of the most reliable products amongst most Americans.
