The World's Strongest Bond™ Just got stronger

J-B Weld is strong. Crazy strong. Rebuild-an-engine-part strong. Fix-broken-metal strong. It's the epoxy adhesive people reach for when a repair absolutely has to hold, and it's been the World's Strongest Bond™ for decades.

So naturally, we made it stronger.

Same J-B Weld you know, now with 25% more strength behind every fix. It's still the strongest epoxy on the market.

What does 6,220 PSI actually mean?

PSI stands for pounds per square inch, and it's how tensile strength is measured. At 6,220 PSI, one square inch of cured J-B Weld can support 6,220 pounds. That's more than three tons hanging on a patch of epoxy about the size of a postage stamp.

For the repairs that really test you

Some repairs don't leave any room for error. A cracked engine part. A snapped bracket. Broken metal that has to take a beating and keep holding. That's where the extra strength earns its keep.

Plenty of strength for the small stuff too

Most repairs never come close to asking for 6,220 PSI. The everyday stuff gets the same strength anyway.

We've got some strength left over.

Already have J-B Weld at home? You're covered.

If the J-B Weld in your garage, toolbox, or junk drawer says 5,020 PSI on the package, you've still got the World's Strongest Bond™. It already packed more strength than most everyday repairs call for, and it's the same J-B Weld people have trusted on tough fixes since 1969. Go ahead and use it with confidence.

The new 6,220 PSI just puts even more strength in your back pocket for the jobs that push the limits.
