Over the years, adhesives have evolved to become stronger, easier to apply and give quality results. In this article, we are going to analyze two of the best adhesives there are in the market. That is the JB weld vs epoxy; compare and contrast between them based on their uses and differences.
By the end of this article, you should be able to make an informed decision about which is best for your project. Read on to know more.
What Is JB Weld?
Uses of JB Weld
JB weld is a versatile bond that is suitable for bonding different surfaces. For example, JB weld can be used to bond the following materials made from;
- Paper and
It is also worth mentioning that JB weld can be exposed to microwave radiation and as such used in a microwave. According to their official Wikipedia page, JB weld is not just an adhesive alone, it is also used as a sealant, filler, plug, and electrical insulator.

Is JB Weld as Good as Welding?
Also known as the original cold weld, JB weld was initially developed as an effective alternative to traditional welding. It is very effective even in extreme conditions due to its two-parts epoxy system. JB weld helps create one of the strongest bonds once it’s set.
All in all, JB weld is structurally strong and can contend with other strong metals such as aluminum.
What Is Epoxy?
Although the word epoxy might not be new to many people, however, not many people know what it is. Epoxy is a common adhesive polymer made of several subunits of chemical compounds consisting of larger molecules. The inner structure of the polymer is what makes it very strong, elastic, and tough.
Some good examples of polymer include Styrofoam, rubber, and epoxy.
There are two types of epoxy adhesive or bond found in the market, and they are;
- Heat cured or one-part epoxy
- Two-part cured epoxies
Heat Cured or One Part Epoxy
These types of epoxies require a lot of heat to cure and have several industrial uses. However, due to its high heat requirement, it is not suitable for use in the construction industry. It is used to bond materials like electronic components.
Two-Part Cured Epoxies
It is called two-part cured epoxy because the two components needed for the job come separately. After it is mixed, it needs 24 hours to cure a liquid substance into a hardened material. The two-part epoxies are used in the automotive and manufacturing industry. And unlike its heat-cured counterpart, it can be used in construction projects.
Uses Of Epoxy
The uses of epoxy range from being used in coatings, paints, and adhesives. Epoxy coatings are UV resistant, hard, and abrasion-resistant. As such, it is used to coat metals and materials that need to withstand wear and tear.
Adhesive epoxy is used most commonly in the construction of automobiles, boats, and bicycles among others. Epoxies are also found in electrical systems, industrial tooling, and marine field among others.
Is JB Weld and Epoxy Same?
Well, this is a bit tricky as JB weld is a form of epoxy but stronger than regular standard epoxy.
Difference Between JB Weld and Epoxy
Below is the main difference between JB weld and epoxy
|Needs 24 hours to cure||Dries very quickly|
|It’s safe in food materials||It’s not safe|
|It is grey in color once cured||It is clear in color|
Both JB weld and Epoxy have their functionalities. It all depends on the desired results. We hope this article provides the necessary information needed for making the right choice.
