Tetramethyl bisphenol F (TMBPF) is a new coating intended as a safer replacement^[1] for bisphenol A and bisphenol F to use in epoxy linings of aluminium cans and steel cans. It was previously suggested as an insulator in electronic circuit boards.^[2]

Polymerization of tetramethyl bisphenol F occurs with epichlorohydrin when heated between 40 and 70 °C using an alkali as a catalyst to form the resin used as a coating.^[3]

Causes serious eye irritation. May cause respiratory and skin irritation. Very toxic to aquatic life.^[4]

TMBPF does not have any effect on the endocrine system; it does not leach out of cans because unlike BPA it is fully polymerized when deposited on the metal, so there is no free chemical to leach out.^[2] Tetramethyl bisphenol F was tested on rats to see if there were effects like male or female hormones. It had almost no effects like this.^[5] However, a different study did find effects.^[6]
