EPONEX™ Resin 1510


EPONEX™ Resins are unique low viscosity epoxy resins designed to have improved performance compared to conventional bisphenol-A (BPA) type resins, when formulated properly. EPONEX Resin 1510 is recommended as a building block resin for preparations of: 1) low viscosity/higher molecular weight epoxide resins  (e.g. by reaction with bisphenol-A) and 2) low viscosity esters using conventional esterification reactants.  It can also be used as a reactive viscosity reducer and a modifier for improved color in BPA-based epoxy resins.  Figure 1 illustrates the typical structure of EPONEX Resins.
