This has led to the term modified epoxy resin to denote those containing viscosity-lowering reactive diluents. [21] The use of the diluent does effect mechanical properties and microstructure of epoxy resins. [22] Mechanical properties of epoxy resins are generally not improved by use of diluents. [22] Biobased epoxy diluents are also available ...
Bisphenol A diglycidyl ether (commonly abbreviated BADGE or DGEBA) is an organic compound and is a liquid epoxy resin. [1][2][3][4][5] The compound is a colorless viscous liquid (commercial samples can appear pale straw-coloured). [6][7] It is a key component of many epoxy resin formulations. Addition of further Bisphenol A and a catalyst and ...
Bisphenol A (BPA) is a chemical compound primarily used in the manufacturing of various plastics. It is a colourless solid which is soluble in most common organic solvents, but has very poor solubility in water. [ 2 ][ 7 ] BPA is produced on an industrial scale by the condensation reaction of phenol and acetone.
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).

The bisphenols (/ ˈbɪsfɪnɒl /) are a group of industrial chemical compounds related to diphenylmethane; commonly used in the creation of plastics and epoxy resins. [1][2][3] Most are based on two hydroxyphenyl functional groups linked by a methylene bridge. Exceptions include bisphenol S, P, and M. "Bisphenol" is a common name; the letter ...
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).
