Bisphenol A diglycidyl ether (abbreviated to BADGE or DGEBA) is a chemical compound that is used as a monomer for the production of epoxy resins and phenolic resins. It is a derivative of bisphenol A, which is also used for epoxy resins, due to its ability to cross-linking. Coatings on the basis of BADGE be used for the inside lining of food cans and screw caps (twist -off lid ). BADGE from these coatings transgressed as unreacted monomer in foods.

The establishment of numerous standard epoxies based on diglycidyl ethers, including BADGE. Epoxy resins are cross-linked by the addition of curing agents. The most common curing agents for epoxy resins are polyamines, amino amides and phenolic compounds.

Toxicology

BADGE is listed as a Group 3 chemical IARC, which means that it is "not classifiable as to its carcinogenicity to humans " is. Since the 1990s, concerns were raised as to carcinogenicity to, especially since BADGE as mentioned occurs with food contact.
