Diglycidyl Ether of Bisphenol A Epoxy Resins

Epoxy resins based on diglycidyl ether of bisphenol A are not only the oldest type of epoxy resins but also the most valuable in adhesive formulations. The primary reasons for their popularity have been [Pg.72]

The relatively low cost of raw materials used to synthesize these resins [Pg.72]

Their ability to be cured by a large number of different crosslinking agents at both room and elevated temperatures [Pg.72]

Their relatively good mechanical and chemical properties that are exhibited by the cured resins [Pg.72]

The DGEBA family of epoxy resins provides superior overall performance in a variety of end-use applications. With proper additives or modifiers, these base polymers enable for-mulators to achieve practically any desired performance level, while optimizing process-ability and durability in many environments. [Pg.72]

The matrices were two DGEB A (diglycidyl ether of bisphenol A) epoxy resins. The hardeners were either 35 parts by weight of diamino diphenyl sulfone (resin I) or 55 parts of polyamino amide (resin II). The curing conditions were 3 h at 130°C followed by 3 h at 180°C for resin I and 24 h at 40°C followed by 6 h at 100°C for resin II. [Pg.186]

Other quinoxaline-type polymers can have higher Tg values, e.g. 400°C. DGEBA stands for diglycidyl ether of bisphenol A. Epoxy resin properties can depend considerably on the hardener used. [Pg.22]

Epoxy resin ceiling temperatures depend crucially on both the epoxy resin and the hardener. The difunctional DGEBA (diglycidyl ether of bisphenol A) epoxy resin system is the most common, producing high heat distortion... [Pg.130]

The thermal properties of the nanocomposites of diglycidyl ether of bisphenol A epoxy resin containing different montmorillonite nanoclays depends on the surface modifications of the nanoclays. Moreover, the addition of nanoclays improved the thermal properties of the nanocomposites, compared to the neat epoxy [59]. [Pg.33]

As a component of non-diglycidyl ether-of-bisphenol-A epoxy resins, brominated epoxy resin caused contact dermatitis in a cleaner of worksites in a condenser factory, in which condensers were filled with a mixture made of an epoxy resin. [Pg.1132]

The most common epoxy resin is based on the diglycidyl ether of bisphenol A. Epoxy resins are sometimes esterified with fatty acids or modified with polyurethane intermediate chains for elastification. [Pg.35]
