What is JB Weld?
If you’re looking for a strong adhesive that can bond almost any surface, you might have heard of JB Weld. It’s a two-part epoxy that was developed as an alternative to traditional torch welding.
JB Weld is a two-part epoxy that consists of a resin and a hardener. When these two components are mixed together, they create a strong and rigid bond that can withstand high pressure and extreme temperatures.
The adhesive is designed to be effective in even the harshest environments, making it a popular choice for automotive repairs and home improvement projects.
Types of JB Weld
JB Weld products come in various forms, including twin tubes, syringes, and putty sticks. The primary difference is in the dispensing method, but all of them consist of two-component epoxies that harden to bond on most surfaces. Here are some of the types of JB Weld products:
| Product Type | Description |
|---|---|
| Twin Tubes | The original! Resins and hardeners are in two separate tubes that you dispense in equal amounts before mixing. |
| Syringes | The resin and hardener are pre-measured and packaged in a syringe for easy mixing and dispensing. |
| Putty Sticks | A two-part epoxy putty that can be molded and shaped to fit the repair area before it hardens. |
JB Weld can be used on a variety of surfaces, including metal, steel, wood, glass, fiberglass, ceramic, ABS, and more.
