As adhesives, epoxies bond in three ways: a) Mechanically, because the bonding surfaces are roughened; b) by proximity, because the cured resins are physically so close to the bonding surfaces that they are hard to separate; c) ionically, because the epoxy resins form ionic bonds at an atomic level with the bonding surfaces.
Fusion bonded epoxy coating, also known as fusion-bond epoxy powder coating and commonly referred to as FBE coating, is an epoxy-based powder coating that is widely used to protect steel pipe used in pipeline construction from corrosion.
It is a precursor in the production of epoxy resins. [19] Halohydrins react with base to give epoxides. [20] The reaction is spontaneous because the energetic cost of introducing the ring strain (13 kcal/mol) is offset by the larger bond enthalpy of the newly introduced C-O bond (when compared to that of the cleaved C-halogen bond).
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]
Araldite epoxy resin is commonly used as an embedding medium for electron microscopy. [9] Some Flamenco guitarists (e.g. Paco Peña) use it to reinforce their fingernails. [10] Brian May used it to seal some of the pickups in his homemade Red Special guitar to reduce microphonic feedback. [11]
CYPC2C9 is known and the other arachidonic acid-metabolizing CYPs are thought to likewise attack linoleic acid at its 9,10 carbon–carbon double bond to form 9S,10R-epoxy-12(Z)-octadecenoic and 9R,10S-epoxy-12(Z)-octadecenoic acid optical isomers; this set of optical isomers is also termed coronaric acid, linoleic acid 9,10-oxide, and leukotoxin.
