BISPHENOL A DIGLYCIDYL ETHER RESIN Chemical Properties,Usage,Production

Description 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.
Description PPARγ is a ligand-activated transcription factor involved in the regulation of lipid homeostasis and may function as a master regulator of adipogenesis. Ligands for PPARγ include antidiabetic drugs of the thiazolidinedione structural class, 15-deoxy-Δ^12,14-prostaglandin J₂ , and NSAIDS. BADGE is a synthetic compound used in the production of polycarbonate and industrial plastics. This compound was recently identified as an antagonist of PPARγ. BADGE binds to PPARγ with an apparent K_d of 100 μM and interferes with the ability of 3T3-L1 and 3T3-F442A cells to undergo hormone-mediated cell differentiation.
Chemical Properties Diglycidyl ether of bisphenol A is a colorless to light amber liquid. Slight epoxy odor.
Uses Bisphenol A derivative. A PPARγ antagonist; exhibits estrogenic activity; An inhibitor of PPARγ and suppressor of TNFα.
Uses The uniqueness of D.E.R. 332 epoxy resin is reflected in its maximum epoxide equivalent weight of 178. Because of its high purity and lack of polymer factions, samples embedded using D.E.R. 322 have uniform performance, exceptionally low viscosity and color; and improved elevated temperature properties.
Uses In the manufacture of epoxy resins and polycarbonates for food packaging.
Definition ChEBI: Bisphenol A diglycidyl ether is a diarylmethane.
Production Methods 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.
General Description 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.
Reactivity Profile 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.
Health Hazard Contact with liquid irritates eyes. Prolonged or repeated contact with skin causes irritation and dermatitis.
Fire Hazard BISPHENOL A DIGLYCIDYL ETHER RESIN is probably combustible.
Biological Activity 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 .
Contact allergens Most epoxy resins result from polymerization of bisphenol A diglycidyl ether (BADGE). Delayed hypersensitivity is caused by the low-molecular-weight monomer BADGE (Molecular Weight 340 g/mol), the dimer having much a lower sensitization power. 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.
Biochem/physiol Actions PPARγ inhibitor that blocks rosiglitazone- and insulin-induced adipogenesis.
Potential Exposure Diglycidyl ether of bisphenol A is used as a basic active ingredient of epoxy resins.
First aid If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit.
Carcinogenicity 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.
storage Color Code—Blue: Health Hazard (skin sensitization): Store in a secure location. Prior to working with thischemical you should be trained on its proper handling andstorage. Store in tightly closed containers in a dark, cool,well-ventilated area away from strong oxidizers, acids, and heat. Recommended storage (and pumping)temperature=45-50℃.
Shipping This material is not covered in DOT’sPerformance-Oriented Packaging Standards. It may,however, be classified as a Combustible Liquid, n.o.s. Thisclass requires no shipping label. It falls in Hazard Class 3[each reference to a Class 3 material is modified to read“COMBUSTIBLE LIQUID” when that material is reclassified in accordance with y173.150 (e) or (f) of this subchapter or has a flash point above 60.5℃/141°F but below93℃/200°F], and Packing Group III. The symbol “D” identifies proper shipping names which are appropriate fordescribing materials for domestic transportation but may beinappropriate for international transportation under the provisions of international regulations (e.g., IMO, ICAO). Analternate proper shipping name may be selected when eitherdomestic or international transportation is involved.
Incompatibilities Easily oxidized in air; presumed to form unstable and explosive peroxides in storage. Incompatible with strong acids; strong oxidizers.
Waste Disposal Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber.
