As an addition to this core study, FDA is providing extra animals and tissues to a consortium of grantees [8] selected and funded by the National Institute of Environmental Health Sciences to address other critical questions. Demonstrated that oral BPA administration results in rapid metabolism of BPA to an inactive form. Epoxy resins are made by reacting epichlorohydrin (ECH) and bisphenol A to produce a different chemical substance called bisphenol A diglycidyl ether (also known as BADGE or DGEBA). At high concentrations, BPA also binds to and acts as an antagonist of the androgen receptor (AR). Bisphenol A epoxy resin is the most common type for concrete coatings because of its excellent adhesion, toughness, abrasion resistance, and chemical resistance. The molecular structure of bisphenol A epoxy resin contains aromatic rings and lateral hydroxyl groups, which is beneficial to improve adhesion; in addition, the aromatic ring structure also gives the resin higher rigidity, tensile strength and thermal stability; in general, The main characteristics of bisphenol A epoxy type include: fast light curing reaction rate, high hardness and tensile strength after curing, high gloss of the film layer, and excellent chemical corrosion resistance. BPA is one of the most thoroughly tested chemicals in use today and has a safety track record of more than 50 years. BPA can both mimic the action of estrogen and antagonise estrogen, indicating that it is a selective estrogen receptor modulator (SERM) or partial agonist of the ER. Another reason for concern, especially for parents, may be because some animal studies report effects in fetuses and newborns exposed to BPA.
