Abstract
A coated article is provided which comprises a metal substrate and an overlying layer of a composition comprising a copolymer of 3,3,3-trifluoro-2-trifluoromethyl propene and vinylidene fluoride and an effective amount of a stabilizing agent. More particularly, the stabilizing agent is present in an amount of at least about 0.2 percent by weight based upon the weight of the copolymer and is selected from the group consisting of the oxides and salts of divalent meatls and mixtures thereof. Preferably, the thickness of the coating on the metal substrate is at least about 1 mil.
