Does JB Weld really work?
The JB should work fine. Just remember to do what Ice suggested about making sure all of the surfaces are totally clean and grease free. If your going to leave a large gap in the joints then work the JB down into the crack and add some on both sides of the metal if possible. Also to know is, will JB Weld work on galvanized pipe?
What is the maximum pressure that JB Weld can withstand?
JB Weld is both water and gasoline resistant and has a tensile strength of 5020 PSI and can withstand up to 550 degrees Fahrenheit. Apply the putty firmly over the hole, working the edges of the product flat against the tank to create a seal.
Is JB Weld as good as welding?
JB Weld is just epoxy glue with some steel powder mixed in. It is good quality epoxy, don’t get me wrong, but it is NOT welding. I suggest that you remove the muffler from the vehicle, put it on your bench and patch the hole with real welding. Oxy-Acetylene welding would work fine. So would TIG welding.
What, exactly, is JB Weld good for?
J-B Weld
- 1:1 mix ratio, 4-6 hour set time and cures in 15-24 hours
- Tensile strength of 5020 PSI
- Metal, plastic & PVC, wood, concrete, ceramic/tile & fiberglass
Is J-B Weld as strong as an actual weld?
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.
Will J-B Weld hold two pieces of metal together?
J-B Weld™ is The Original Cold Weld two-part epoxy system that provides strong, lasting repairs to metal and multiple surfaces. Mixed at a ratio of 1:1, it forms a permanent bond and can be shaped, tapped, filed, sanded and drilled after curing.
How strong is original J-B Weld?

What is the strongest glue for metal to metal?
Epoxy adhesivesEpoxy adhesives form the strongest metal-to-metal bonds. They consist of two parts – the adhesive and the hardener. These combine to create strong, long-lasting bonds between different types of metal or between metal and concrete surfaces.
What's the strongest JB Weld?
J-B Weld has a tensile strength of 3960 PSI and sets to a hard bond overnight. It can withstand temperatures up to 550ºF when fully cured.
What is the compression strength of J-B Weld?
3960psiTo ensure a quality repair, make sure you clean all surfaces, and in many cases, scuffing will ensure a great bond. The original two-pot cold weld is a steel-reinforced epoxy that sets so hard (compressive strength of 3960psi) that it can be drilled, tapped, shaped, and sanded once fully cured.
Why is my J-B Weld not getting hard?
It stays soft for a few hours. That said, insufficient curing could be caused by several factors, the most important of which is: MIX REALLY REALLY THOROUGHLY. Scrape the surface of the mixing stick, and the container/surface you're mixing on, and then scrape them again.
Which is stronger J-B Weld or epoxy?
Weld was accualy better than epoxy. Not price wise, but its quality. JB Weld actually is stronger, but not enough to make it worth it. It's very hard to get smooth.
What is the shear strength of JB Weld?
To provide for a variety of uses, JB Weld SuperWeld comes in a 2-pack version with small 2g tubes for single use this has a shear strength of 3100PSI. It is also available in a brush cap 6g bottle for brush-on applications, it has a sheer strength of 3000 PSI.
What is the strongest epoxy for metal?
The best epoxy for metal is Loctite Epoxy Metal/Concrete, a two-part system consisting of an epoxy resin and a hardener. The resin and hardener are combined to create a durable, high-strength bond that dries in minutes and can be used for repairing, filling, and rebuilding all metal and concrete surfaces.
Can I use JB Weld on metal?
J-B Weld Original can be used to repair many different materials including metal, wood, plastic, ceramic, fibre glass, brick, concrete and much more.
History
The company had its beginnings in 1969 in Sulphur Springs, Texas. Sam Bonham, at the time running a machine shop, discovered a way to create what he called a "tougher than steel" epoxy. In 1968, Sam's future wife Mary persuaded him to sell his invention and he founded the J-B Weld Company. Sam died suddenly in 1989.
Products
The J-B Weld Company's original product line focused on a small number of products: J-B Weld (original 2-tube epoxy), J-B Kwik (4-hour epoxy), J-B Stik ( epoxy putty ), Waterweld (underwater adhesive/filler), and a few others.
J-B Weld epoxy
J-B Weld is a two-part epoxy adhesive (or filler) that can withstand high-temperature environments. J-B Weld can be used to bond surfaces made from metal, porcelain, ceramic, glass, marble, PVC, ABS, concrete, fiberglass, wood, fabric, or paper. Alcohol should be avoided when cleaning surfaces, as it can degrade the bond.
Is silicon a bad heat conductor?
Silicone as such is not a "bad" heat conductor , it's all the other stuff in the product that controls how well it will do as a heat transfer agent . There are other reasons not to use RTV around electronics , mainly having to do with the acid given off on cure. badfish34668. Ars Praefectus.
Is JB weld conductive?
Yeah JB Weld has reasonable thermal conduction, but as stated it is a permanent bond (fine for putting sinks on ram chips and chipsets), so you do not want to use it on a processor. I also think it is electrically conductive so any spillage or slop will short/ruin electronics.
What is JB weld?
JB Weld SteelStick is a steel reinforced epoxy putty. That means it has steel flakes in it, as a filler. The steel flakes work like fiber reinforcement would, making the cured JB Weld a very hard mass. Once cured, JB Weld can be drilled filed and tapped, making it ideal for automotive or machinery repairs.
What is JB Weld epoxy putty?
In addition to the liquid epoxy that JB Weld makes for wood, they also provide an epoxy putty specifically formulated for working with wood. I believe this is the only epoxy putty specially formulated for wood that's available on the market. It is specifically formulated to use as a filler, repairing and rebuilding wood that has become damaged. It contains no solvents, so it will not stain, or leave any chemical residue which will soak through paints and other finishes. The epoxy putty has a 15 to 25 minute work life and fully cures in one hour. Cured, this epoxy putty provides 900 PSI of tensile strength. It can be machined (including drilling, tapping and sanding once it is cured) while the light tan color accepts paint well.#N#Read More Close
What is Bob Smith epoxy?
This fast-curing epoxy from Bob Smith Industries cures to a slightly flexible consistency. This makes it perfect for use in applications where there is high vibration or substrates that are not totally rigid. This adhesive works with a wide range of substrates, including unusual ones like soft woods, hard plastics and white foam. Although it doesn't have the highest tensile strength, it cures quickly, giving you five minutes of working time and parts that are ready for handling in 15 minutes. It can be coated with polymer resin without affecting the curing of the resin, something that not all epoxies can do. Mixing it with microballoons (also available from Bob Smith) allows it to be used as a quick-setting putty, great for filling and repairing damaged wood. Packaged in two, four ounce bottles.#N#Read More Close
What is T-88 epoxy?
T-88 is a true structural adhesive, which can be used for attaching wood parts together where fasteners might not be applicable, due to difficulty of installing the fasteners or expected problems with holding power. This epoxy cures to a transparent amber color that all but disappears when varnished. It is unique in that it can even be used on damp wood, without loss of strength. As long as the epoxy is worked into the wood with a brush. It's also incredibly strong, offering a tensile strength of 7,000 PSI when cured. It does not shrink when curing and remains flexible (even when fully cured) and will cure in temperatures as low as 35oF. The cured epoxy is unaffected by water, oil, kerosene and many other chemicals.#N#Read More Close
How long does it take for JB welding to cure?
It handles high temperatures well, up to 300 degrees, making it ideal for vehicle exhaust systems. The putty sets in five minutes and fully cures in 1 hour, resulting in a final strength of 900 PSI.
Why is it so hard to bond plastic?
Plastic Epoxy. Plastics can be difficult to bond together due to their variety in hardness, texture and natural oiliness. But getting the plastics to bond isn't the whole battle. Once bonded, many plastics will fail either at the bond itself or at the edge of the adhesive.
Where are epoxy woodworking tools made?
It has a spreader, two mixing sticks, a video tutorial, and a foam brush. The epoxy materials are made in America, thus guaranteeing only top quality materials which will stand the test of time.
