Bisphenol A diglycidyl ether slowly hydrolyzes to 2,2-bis[4(2,3-dihydroxypropoxy)phenyl)propane (bis-HPPP). Similarly, DGEBA reacts with acrylic acid to give vinyl ester resins . The reaction results in opening of the epoxide ring, generating unsaturated esters at each terminus of the molecule.
Bisphenol A (BPA) is a chemical compound primarily used in the manufacturing of various plastics. ... BPA diglycidyl ether (BADGE) is used as an acid scavenger, ...
Diglycidyl ether itself is extremely toxic, and can prove fatal or cause permanent damage if inhaled or consumed orally. As a class of compounds, there are a number of them available commercially with much lower toxicity profiles. [3] [4] One such example is epoxy resin itself Bisphenol A diglycidyl ether.
Bis-GMA a typical "vinyl ester" derived from bisphenol A diglycidyl ether. This thermoset material can be used as an alternative to polyester and epoxy materials as the thermoset polymer matrix in composite materials, where its characteristics, strengths, and bulk cost are intermediate between polyester and epoxy. Vinyl ester has lower resin ...
Tetrabromobisphenol A diglycidyl ether is an epoxy resin consisting of tetrabromobisphenol A with ether linkages to two epichlorohydrin groups. An alernative structural comparison is as brominated form of bisphenol A diglycidyl ether. It is a brominated aromatic chemical used principally for giving flame retardant properties to materials.

Bisphenol A Diglycidyl ether-based epoxy coatings are extensively used for coating the inside of cans which come into contact with food and are thus food contact materials. The materials and analogues and conjugates have been extensively tested for and analytical methods developed.

The most common epoxy resins are based on reacting epichlorohydrin (ECH) with bisphenol A, resulting in a different chemical substance known as bisphenol A diglycidyl ether (commonly known as BADGE or DGEBA).
