BISPHENOL A DIGLYCIDYL ETHER RESIN Usage And Synthesis
Most epoxy resins result from polymerization of bisphenol A diglycidyl ether (BADGE). Delayed hypersensitivity is caused by the low-molecular-weight monomer BADGE (MW 340 g/mol), the dimer having a much lower sensitization power. This allergen caused contact dermatitis in six workers in a plant producing printed circuits boards made of copper sheets and fiberglass fabric impregnated with a brominated epoxy resin. It can also be contained in adhesives.
Diglycidyl ether of bisphenol A is a colorless to light amber liquid. Slight epoxy odor.
Bisphenol A derivative. A PPARγ antagonist; exhibits estrogenic activity; An inhibitor of PPARγ and suppressor of TNFα.
In the manufacture of epoxy resins and polycarbonates for food packaging.
The synthesis of the basic epoxy resin molecule involves the reaction of epichlorohydrin with bisphenol A, the latter requiring two basic intermediates for synthesis, acetone and phenol. Theoretically, the production of the bisphenol A diglycidyl ether requires 2 mol of epichlorohydrin for each mole of the phenol. Epoxy resins of higher molecular weight are obtained by reducing the epichlorohydrin/bisphenol A ratio. This reaction involves consumption of the initial epoxy groups in the epichlorohydrin and of some of the groups formed by dehydrohalogenation.
Odorless yellowish brown liquid. Sinks in water.
Air & Water Reactions
Oxidizes readily in air to form unstable peroxides that may explode spontaneously [Bretherick 1979 p.151-154, 164]. Insoluble in water.
Epoxides, such as BISPHENOL A DIGLYCIDYL ETHER RESIN, are highly reactive. They polymerize in the presence of catalysts or when heated. These polymerization reactions can be violent. Compounds in this group react with acids, bases, and oxidizing and reducing agents. They react, possibly violently with water in the presence of acid and other catalysts.
Contact with liquid irritates eyes. Prolonged or repeated contact with skin causes irritation and dermatitis.
BISPHENOL A DIGLYCIDYL ETHER RESIN is probably combustible.
PPAR γ pure antagonist with micromolar affinity in 3T3-L1 and 3T3-F442A preadipocyte cells; selective over PPAR δ and PPAR α . Antagonizes the ability of rosiglitazone to stimulate transcriptional activity of PPAR γ . Acts as a PPAR γ agonist in an ECV304 cell line. Also produces PPARg-independent apoptosis of tumor cells via several mechanisms. Active in vivo .

This allergen caused contact dermatitis in six workers in a plant producing printed circuits boards made of copper sheets and fiber glass fabric impregnated with a brominated epoxy resin. It can be contained in adhesives.
Diglycidyl ether of bisphenol A is used as a basic active ingredient of epoxy resins.
In summary, a number of carcinogenicity studies involving the topical application of pure BADGE as well as EPON Resin 828 and other commercial BADGE-based resins have been carried out in experimental animals.Viewing the studies as a whole, the weight of evidence does not show that BADGE or BADGE-based epoxy resins are carcinogenic.
Easily oxidized in air; presumed to form unstable and explosive peroxides in storage. Incompatible with strong acids; strong oxidizers.
Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber.
