Abstract:
An article wherein at least a part of the surface of said article is coated with a coating layer formed from an aqueous fluoroelastomer curable coating composition;wherein said coating composition comprises an aqueous fluoroelastomer dispersion, a basic salt of a compound containing at least two phenolic hydroxyl groups as a curing agent, and a curing accelerator selected from the group consisting of salts of tertiary amines of the formula NR3 with inorganic or organic acids and salts of tertiary amines of the formula R2Nâ€”Râ€²â€”NR2 with inorganic or organic acids, wherein each of said R groups is the same or different from each other and each is an alkyl or alkenyl group having 1 to 20 carbon atoms, or an aryl group having 6 to 20 carbon atoms, or two or more R groups together form a carbon ring or a heterocyclic group, and Râ€² is an alkylene group having 2 to 21 carbon atoms or a phenylenedialkylene group having 8 to 12 carbon atoms; wherein said aqueous fluoroelastomer dispersion in said coating composition comprises a fluorine-containing elastic copolymer having repeating units represented by the formula: â€”CH2â€” in the backbone.
