Bisphenol A diglycidyl ether (commonly abbreviated BADGE or DGEBA) is an organic compound and is a liquid epoxy resin.

The reaction results in opening of the epoxide ring, generating unsaturated esters at each terminus of the molecule.

The most common curing agents for epoxy resins are polyamines, aminoamides, and phenolic compounds.

[11] Hydrolysis of the ether bonds liberates bisphenol A, which is also strongly suspected of being an endocrine disruptor.

[12][13] From the 1990s onward, concern has been raised over the use of BADGE-based epoxy resins in the lining of some cans for foodstuffs, with the chemical being found to leach into foods.
