J-B Weld (stylized as J-B WELD) is the name of their flagship product: a specialized, high-temperature epoxy adhesive for use in bonding materials together. The company has run advertisements showing engine block repair with J-B Weld. [2] The J-B Weld Company, founded in 1969 by Sam Bonham in Sulphur Springs, Texas, specializes in epoxy products.
The first batches of Araldite epoxy resins, for which the brand is best known, were made in Duxford, England in 1950. [1] Araldite adhesive sets by the interaction of an epoxy resin with a hardener. Mixing an epoxy resin and hardener together starts a chemical reaction that produces heat – an exothermic reaction. [2]
An epoxy may be used for mounting, but can lead to failure in the epoxy/polymer interface instead of in the bonded joint. [2] The most common method for testing solvent bonds is the tensile shear test using a lap joint configuration.
Epoxy is the family of basic components or cured end products of epoxy resins. Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups. The epoxide functional group is also collectively called epoxy. [1] The IUPAC name for an epoxide group is an oxirane.
Monomers characterized by high functionality tend to undergo gelation at a lower level of reaction, yet they possess an increased capacity for cross-linking. To achieve a matrix exhibiting elevated modulus and glass transition temperature, a higher degree of crosslinking is essential, which is a prerequisite for effective post-curing. [5]
The components of the FBE formulation are weighed and pre-blended in high speed mixers. The mix is then transferred to a high-shear extruder. FBE extruders incorporate a single or dual screw setup, rotating within a fixed clamshell barrel. A temperature range [vague] from 50 °C to 100 °C is used within the extruder barrel. This setup ...
