Sampson, William (September 16, 2013). "In the Shop: Wood repair products from J-B Weld". www.fdmcdigital.com. CabinetMakerFDM . Retrieved March 27, 2015. Since 2008, the company has broadened the product line to add J-B SteelStik, KwikWood, PlasticWeld, MarineWeld, Perm-O-Seal, WoodWeld and ClearWeld. [5] [6] J-B Weld epoxy [ edit ] 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] Electric Insulation. You can find plenty of plastic automotive glue that works as an electric insulator. If you're looking to secure exterior pieces or seal a seam, this may not be necessary. However, don’t forget how much wiring there is in your vehicle. The amount of electrical parts means there are plenty of interior locations and spots in the engine that need extra electricity protection.

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.This article relies excessively on references to primary sources.

Container Size. The amount of automotive glue you need depends on what you're trying to accomplish and how often you plan to use it. If you only have a small area to fix, then a small-sized container should handle the job. Mechanics will most likely want a larger portion or multiple containers to handle a more significant workload. 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. It hardens in 5 minutes and cures in 10 minutes. It works well under a maximum temperature of 315°C (<100 continuous). It contains 54g/l solvent. It is not suitable for soft plastic and polypropylene. 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. To use Super Steel Epoxy make sure the surfaces to be bonded are clean and dry and free from oil, dirt or grease.It is a good idea to clean the surfaces with methylated spirit or cellulose thinners and to roughen the surfaces before applying. Also, adding reinforcement can increase the strength of the joint. Bonding additional pieces of wood or metal over an epoxied joint can mechanically stiffen the joint and help it to better withstand the variety of forces that act on it. 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] My encounter with JB-Weld at Tractor Supply was an itch I had to scratch. I bought two types of J-B Weld and brought them into the Popular Mechanics shop in an attempt to find out, just how tough this repair material really is. 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.
