Bisphenol A diglycidyl ether (commonly abbreviated BADGE or DGEBA) is a chemical compound used as constituent of epoxy resins. It is a derivative of bisphenol A that is used in epoxy resins for its cross-linking properties.
Many standard epoxies are based on a formula containing diglycidyl ethers, including BADGE. Epoxy resins are crosslinked using hardeners (curing agents). The most common curing agents for epoxy resins are polyamines, aminoamides and phenolic compounds.
BADGE is listed as an IARC Group 3 carcinogen, meaning it is "not classifiable as to its carcinogenicity to humans". From the 1990s onward, concern has been raised over this possible carcinogenicity because BADGE is also used in epoxy resins in the lining of some tin cans for foodstuffs, and unreacted BADGE may end up in the contents of those cans.
