[12] [13] From the 1990s onward, concern has been raised over the use of BADGE-based epoxy resins in the lining of some cans for foodstuffs, with the chemical being found to leach into foods. [ 12 ] [ 14 ] Bisphenol A Diglycidyl ether-based epoxy coatings are extensively used for coating the inside of cans which come into contact with food and ...
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.
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]
Vinyl ester resin, or often just vinyl ester, is a resin produced by the esterification of an epoxy resin with acrylic or methacrylic acids. [1] The "vinyl" groups refer to these ester substituents, which are prone to polymerize and thus an inhibitor is usually added.
They are used extensively in epoxy formulation in North America [3] [4] but its use has been phased out in Europe. [5] These compounds are also precursors to the commercially important non-ionic surfactants alkylphenol ethoxylates and nonylphenol ethoxylates, which are used in detergents , paints, pesticides , personal care products, and plastics.
A compound containing the epoxide functional group can be called an epoxy, epoxide, oxirane, and ethoxyline. Simple epoxides are often referred to as oxides. Thus, the epoxide of ethylene (C 2 H 4) is ethylene oxide (C 2 H 4 O). Many compounds have trivial names; for instance, ethylene oxide is called "oxirane".
As an Epoxy modifier it is classed as an epoxy reactive diluent. [8] It is also used to synthesize other molecules. [9] The use of the diluent does effect mechanical properties and microstructure of epoxy resins. [10] [11] It has been used to simultaneously increase cryogenic strength, ductility and impact resistance of epoxy resins. [12]
Loctite is an American [1] brand of adhesives, sealants, surface treatments, and other industrial chemicals that include acrylic, anaerobic, cyanoacrylate, epoxy, hot melt, silicone, urethane, and UV/light curing technologies. Loctite products are sold globally and are used in a variety of industrial and hobbyist applications.
