Who invented jb weld

The brand has expanded into more areas with many more products, all designed to help make repairs easier and lasting. To that end, there is some education that comes with JB Weld. Not all bonds are the same. There are many types of glue and epoxy, which ones is best for your parts depends on the material and application involved. There are three types of adhesive cure- evaporative, reactive, and chemical. Evaporative cure is what it sounds like, the moisture from the glue slowly evaporates, leaving the glue to harden, making the bond.

This is a mechanical bond, the two parts are held together by the glue itself, they do not become one again. This mechanical bond can be very strong, stronger than the substrate parts themselves. These glues are usually made from natural resins, such as plant and animal tissues.

Reactive cure adhesives are single component adhesives that cure chemically, this is a 1C class adhesive. You might ask how can a single component cure through a chemical process without a second component, and you would be right. The second component in most cases is air. This is different from evaporative cure, when it is a matter of drying, whereas reactive curing is a chemical reaction with the adhesive air, moisture, heat or radiation. There is another version which is anaerobic, or the absence of air, wherein the chemical reaction occurs when oxygen is not present.

Types of 1C adhesives include silicon, cyanoacrylate super glue , caulking, and threadlocker. Two-component adhesives are commonly referred to as 2k or epoxy. JB Weld is an epoxy that consists of an equal ratio mix of resin and hardener. When left unmixed, the two components have a very long shelf life, but when mixed, the reaction begins and the adhesive begins to solidify. There are many types of 2k adhesives, and they are the strongest type of adhesive bond there is.

Modern vehicles are actually built using MMA adhesives, the metal is glued together using the MMA adhesive in many instances, including the unibody chassis itself. These adhesives are so strong, the metal itself will tear before it separates from the adhesive. Most epoxies and 2k adhesives are not tolerant of ratio errors, but JB Weld is simple to meter and mix. The tube versions require you to meter the components out, but most JB Weld adhesives are available in a syringe that has a double plunger, so you get the perfect ratio every time without worry.

Their putty sticks also allow for easy measuring as you simply slice off however much you need. JB Weld makes quite a few products for both automotive and household needs. The great part about it is that the same kit you use to fix the broken ear on your water pump can be used to fix the broken tray in your refrigerator.

For glass, they have a windshield chip repair system and several glues for bonding plastic and metal to glass, which is a difficult task, especially for rear view mirrors. JB Weld is more than just a quick-fix product, it is a permanent solution for hard to repair problems. Strip a bolt hole in your engine block or cylinder head?

Fill it with JB Weld original, drill and tap. Leaky Gas tank? Know How. A life-long gearhead, Jefferson Bryant spends more time in the shop than anywhere else.

His career began in the car audio industry as a shop manager, eventually working his way into a position at Rockford Fosgate as a product designer. In , he began writing tech articles for magazines, and has been working as an automotive journalist ever since. Jefferson has also written 4 books and produced countless videos. Carbon Black The name says it all. Made up of sooty bits often produced by burning hydrocarbons, it gives the resin its inky color.

Calcium Carbonate A cheap filler, found in both the resin and the hardener. Like the silica, it gives the product more volume while decreasing the cost per ounce. All that cross-linking forms a super-strong network structure—a thermoset polymer. When it hardens, J-B Weld can withstand forces of nearly 2 tons per square inch and temperatures up to degrees Fahrenheit. DMP The curing agent on its own is kind of lackadaisical at opening the rings, so epoxies often use accelerators like this one.

Electric Vehicle Network Expansion. Innovative Products. November 22, In the automotive service world there are several brands that are recognised immediately for quality and J-B Weld most certainly fits that bill. ClearWeld, with a syringe applicator and no-mess cap, dries clear. These two-part epoxy putty sticks can prove invaluable in quick repairs — Waterweld offering the additional benefit of curing underwater.
