This technology we use to assemble our list depends on a variety of factors, including but not limited to the following: 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] 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.

SURFACE APPLICATIONS: Iron & Stainless Steel, Copper & Brass, Aluminum & Bronze, Fiberglass and Plastic & PVC. To use Super Steel Epoxy make sure the surfaces to be bonded are clean and dry and free from oil, dirt or grease. compare https://www.jbweld.com/product/clearweld-syringe vs. https://www.jbweld.com/product/j-b-weld-twin-tube

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. It is a good idea to clean the surfaces with methylated spirit or cellulose thinners and to roughen the surfaces before applying. 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. 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. Applications: Abs, Pvc & Cpvc Pipes And Plastics, Auto Bumpers And Trim, Vinyl Surfaces And Siding, Marine Repairs & Fiberglass Parts, Plastic Water Tanks, And Plumbing

The Plastic Padding Super Steel Epoxy Weld is a dark-grey coloured, metal-filled, two-component adhesive, which sets like steel and is ideal for emergency repairs around the home, garden, farm, car, boat etc. There are a few automotive aphorisms that people dispense like hot dogs at a barbecue when what you really want is a cheeseburger. One is, after seeing a photo of an accident, “That’ll buff out.” Another is “LS1 it” (drop a Corvette engine in a car in need of a motor, usually a woeful rat of a car worth less than the LS1). Both sayings are usually offered with a heavy dose of irony. But a third, “Just J-B Weld it,” is often said seriously. 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.

CURE AND SET TIME: After mixing the tubes at a 1:1 ratio, it takes 4-6 hours to set and 15-24 hours to cure. Once cured J-B Weld Original can be tapped, filled, sanded, molded and drilled. J-B Weld Original set and cure color is dark grey. Surface prep is key. Clean is good, but rough is better. The epoxy needs to grab onto the surface. If there are edges, the epoxy can grab on to, the adhesion will be better. 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 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.

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.

In February 2018, I prepared to take the car to the museum. Cure And Set Time: After Kneading The Two Part Formula Together By Hand, Plasticweld Takes 25 Minutes To Set And Cures In 3 Hours.

Rob Siegel J-B Weld is a two-part epoxy adhesive (or filler) that can withstand high-temperature environments.

The Plastic Padding Super Steel comes in two tubes. 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: 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.

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. a b c d e f "Repair Products UK Ltd: Metal Glue - J-B Weld", Repair Products UK Ltd, 2009, RProducts-42.
