Which bond beats all?

If a project or repair involves bonding, the success will likely depend on reaching for the right type of adhesive. This quick guide will help you know the difference between them.

The Power of Epoxies.

An epoxy consists of two separate components: resin and hardener. When mixed and applied to a surface, they create a bond that's stronger than any other type of adhesive. Epoxies are also versatile and can be used for DIY projects, auto repairs, construction and crafting.

Among adhesives, epoxies rate the highest in PSI (Pounds Per Square Inch). But perhaps more important, they also have incredibly high Shear Strength, which measures how well a bond remains intact under force from any direction.

This means the bond created by epoxies isn't just strong, it's lasting. If you use the right type of epoxy for the conditions (waterproof, high heat, etc.) you can expect that bond to endure, even under extreme stress and weather changes.

The versatility of epoxies makes them a great choice for many projects. Whether you're working with wood, metal, ceramics, glass, stone, or other materials, there's an epoxy designed to help you get the job done.

The Instant Appeal of Super Glue.

For quick fixes or urgent situations, a super glue really comes in handy. Most super glues cure within a few minutes, a huge benefit. But their bond is often temporary, and their strength is limited to one direction. That said, when speed matters most, J-B Weld's SuperWeld™ Light Activated Glue is the fastest of the fast, curing in just a few seconds.

White Glue, for Crafts and Kids.

For school projects or lightweight crafts, traditional glue or white glue is a good choice. It's simple to use, safe for kids, and doesn't dry right away so you can often make adjustments easily. Just don't ask too much of it when it comes to strength, and you'll be happy with the results.

Epoxy for the win.

Because of their unbeatable strength, versatility and endurance, epoxies are the right choice for a lasting bond. While it's good to have super glue and white glue handy for quick fixes or light duty crafts, an epoxy will give you the best results for projects around your home. As a maker of heavy-duty epoxies, J-B Weld is known as the World's Strongest Bond. So, whether you're crafting, building or repairing J-B Weld's easy-to-use epoxies will give you strength that lasts.

Nothing Performs Better
Than J-B Weld Epoxies

J-B Weld, known as "The Original Cold Weld," was developed as an alternative to traditional torch welding. It's designed to be extremely effective in even the harshest environments. Because it's a two-component (or 2k) epoxy system, it uses reactive chemistry to create the strongest bond possible. Think of it as having a cross-woven pattern that provides extra strength, much like rebar does to reinforce cement structures. And once it sets, it's tougher than steel. All of our epoxy products are based on this same chemistry, making them the best choice for any project you need to tackle. Plus they're extremely easy to use, whether you choose the original twin tubes, the putty sticks, or the syringes.

Follow Best Practices
For The Best Results

Every adhesive project requires good preparation to be successful. You can ensure J-B Weld will perform to its maximum when you prepare and use it according to the package instructions. You'll also want to prep the area to be repaired. For best results, use a detergent or degreaser to first clean the surface. Then roughen it with a file or coarse sandpaper. This will help create a successful and long-lasting bond.

Since the epoxy was 2-part putty, it was easy get the epoxy to penetrate the PVC pipe in the cut area and get a good seal. It sealed and I have been monitoring the repaired area for almost a month - absolutely no signs any moisture leakage now!
