J-B WELD ORIGINAL PRO SIZE: Professional 5 OZ Tubes of the Original Cold Weld two-part epoxy system that was designed as an alternative to torch welding. J-B Weld Original provides strong, lasting repairs to multiple surfaces and creates a bond stronger than steel. Perfect for DIY household, automotive, marine, craft repair and much more. PRODUCT FEATURES AND STRENGTH: J-B Weld WaterWeld has lap shear strength of 1300 PSI, can withstand continuous temperatures up to 300F (149C) and intermittent temperatures of 350F (176 degrees Celsius) and is chemical resistant against petroleum, hydraulic fluids and other chemicals when fully cured.

Most epoxies add strength to a joint when the epoxy-joint layer is minimized. Epoxy, in and of itself, doesn’t carry strength. Its the cross-linking nature of the epoxy establishing bonds between the materials forming the joint. Long spans (think gaps) between the articles forming the joint creates a weak bond- the epoxy is making longer bonds to the materials to be joined. A thin gap is best. JB Weld has small metallic materials in suspension, so some gap filling will work with this original formulation. compare https://www.jbweld.com/product/clearweld-syringe vs. https://www.jbweld.com/product/j-b-weld-twin-tube So, what do these results tell us? Cheap five-minute epoxy isn’t terrible, and actually better than the fancy new versions of JB Weld. Loctite is okay, and the Devcon and original JB Weld are at the top of their game. That’s not that surprising, as you can cast cylinder heads for engines out of JB Weld. J-B Kwik (stylized as J-B KWIK) is a two-part epoxy, intended as an adhesive or filler, that can withstand medium-temperature environments (up to 300°F or 149°C). [14] PRODUCT FEATURES AND STRENGTH: J-B Weld SteelStik has lap shear strength of 900 PSI, can withstand continuous temperatures up to 350F (176C ) and intermittent temperatures of 450F (232C), and is chemical resistant against petroleum, hydraulic fluids and other chemicals when fully cured. SteelStik can be molded, shaped, sanded, drilled and tapped.

CURE AND SET TIME: After kneading the two part formula together by hand, WaterWeld takes 25 minutes to set and cures in 1 hour. J-B Weld WaterWeld set and cure color is off white.

When the contents of the tubes are thoroughly mixed, the curing process begins and you have a short period to place and use the mixture. The mixture hardens and soon cures to be as strong as steel. Features & Benefits: But an oil leak onto the exhaust threatened to derail the trip. The leak was due to the valve cover stud in the lower left corner of the head being stripped in its hole and thus not tightening, which prevented that corner of the valve cover from sealing. This caused oil to drip directly onto the downpipe, which was a clear fire hazard. At the time, I repaired the stripped threads with a Time-Sert (helicoil). The car still appeared to be weeping a small amount of oil through the threads onto one of the exhaust studs, but this is a common problem, as the lower exhaust studs thread directly into oil runoff area on the low side of the head. I made it home without incident, and that spring I road-tripped the car 2000 more miles to other events. While J-B Weld Original epoxy dries to a dark grey color, [10] J-B Weld's ClearWeld epoxy dries clear. [11] Although its bond is not quite as strong as the Original's (3900 psi vs. 5020 psi), [12] ClearWeld is often preferred when appearance is an important consideration. [13] J-B Kwik epoxy [ edit ]VERSATILE AND DEPENDABLE: J-B Weld Original is steel reinforced, has a tensile strength of 5020 PSI and can withstand temperatures up to 550 degrees Fahrenheit (287 degrees Celsius. When fully cured, J-B Weld Original is waterproof and resistant to petroleum, chemical and acid. Applications: Abs, Pvc & Cpvc Pipes And Plastics, Auto Bumpers And Trim, Vinyl Surfaces And Siding, Marine Repairs & Fiberglass Parts, Plastic Water Tanks, And Plumbing Even though it’s still not leaking, I don’t really consider this a permanent or semi-permanent repair. However, I am continuing to drive the car, maximizing its use until the snow moves into New England. At that time, I’ll pull the head and probably try to find a replacement. The company had its beginnings in 1969 [3] 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. [3] 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. He had commented before his death, "My life's dream is for J-B Weld to be all the way around the world, and for me to see an 18-wheeler load out of here with nothing but J-B Weld." [3] Within a year of his death, Mary had opened a European hub in London, internationalizing the J-B Weld Company and the distribution of the product. [3] J-B Weld can be used as an adhesive, laminate, plug, filler, sealant, or electrical insulator. [8] When fully cured, J-B Weld can be drilled, formed, ground, tapped, machined, sanded, and painted. [8]

Two-part epoxy is one of those must-have items in your toolbox, albeit kept in a ziploc bag to keep all that goo off the rest of your tools. It’s a glue with a million uses, but which brand is best? Should you keep some cheap five-minute epoxy around, or should you splurge for the fancy, long-setting JB Weld. It’s not a perfect analysis, but at least [Project Farm] has done the experiment. This is a test of which two-part epoxy you can find at your local home supply store is strongest. The epoxies tested include Gorilla epoxy, Devcon Plastic Steel, Loctite Epoxy Weld, JB Weld original, JB Weld Kwik Weld, and JB ExtremeHeat. This more or less covers the entire gamut of epoxies you would find in the glue aisle of your local home supply store; the Gorilla epoxy is your basic 5-minute epoxy that comes in a double barrel syringe, and the JB Welds are the cream of the crop. Me and the car at the “2002: ICON” exhibit at the BMW CCA Foundation Museum in Greer, South Carolina. Rob Siegel I made it 230 miles to Harmony, Pennsylvania, by nightfall, and I pounded out the remaining 620 miles to Boston the following day without incident.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. [7] [8] Alcohol should be avoided when cleaning surfaces, as it can degrade the bond. [9] To use Super Steel Epoxy make sure the surfaces to be bonded are clean and dry and free from oil, dirt or grease. Apply the resin to both surfaces to be joined and clamp or tape the parts together until Super Steel has set hard. a b c d e f "About J-B Weld Company", ChemicalWIKI.com, 2020, https://chemicalwiki.com/j-b-weld-incorporated/ JB-WELD about]

After the initial setting period of a few hours, heat (e.g. from a heat lamp or incandescent light bulb placed near the bond) will speed the curing time. [2] [7] And, regarding my BMW 2002tii, if the J-B Weld patch fails and I can’t find a replacement cylinder head, I can always, you know, just LS1 it. Then, the 2002tii was accepted into an exhibit in the BMW Car Club Foundation’s museum in Greer, South Carolina, that commemorated the 50th anniversary of the BMW 2002. In February 2018, I prepared to take the car to the museum. SURFACE APPLICATIONS: Iron & Stainless Steel, Copper & Brass, Aluminum & Bronze, Fiberglass and Plastic & PVC.
