The disclosed curing agents or initiators have the formula MLn(O-SO2-Rf)m wherein L is an imidazole, M is a metal, n is a coordination number of M, Rf is a fluorinated alkyl group, and m is the valence of M. These curing agents are useful in latent curable epoxy systems. Upon heating to the cure temperature (e.g. 100 DEG - 250 DEG C.), such systems cure efficiently and with a low exotherm. |
