It is primarily used as a curing agent or hardener in epoxy chemistry. This can be on its own or reacted with tall oil fatty acid (TOFA) and its dimer to make an amidoamine. [2] This amidoamine is then used as the curing agent for epoxy resin systems. TEPA is a pentadentate ligand in coordination chemistry.
Bisphenol A diglycidyl ether slowly hydrolyzes to 2,2-bis[4(2,3-dihydroxypropoxy)phenyl)propane (bis-HPPP). Similarly, DGEBA reacts with acrylic acid to give vinyl ester resins . The reaction results in opening of the epoxide ring, generating unsaturated esters at each terminus of the molecule.
The epoxy value is defined as the number of moles of epoxy group per 100g resin. So as an example using an epoxy resin with molar mass of 382 and that has 2 moles of epoxy groups per mole of resin, the EEW = 382/2 = 191, and the epoxy value is calculated as follows: 100/191 = 0.53 (i.e. the epoxy value of the resin is 0.53). [6]
The resin's epoxide groups have reacted with the hardener. The material is highly crosslinked and contains many OH groups, which confer adhesive properties. During the curing process, single monomers and oligomers, mixed with or without a curing agent, react to form a tridimensional polymeric network.
It is a common monomer used in the production of epoxy resins. While typical home epoxies contain diglycidyl ether of bisphenol A (DGEBA), glycidyl methacrylate is instead used to provide epoxy functionalization to polyolefins and other acrylate resins. Glycidyl methacrylate is produced by several companies worldwide, including Dow Chemical. [2]

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.
