ABSTRACT:
Improved autodeposited coatings on metallic surfaces are formed by contacting the metallic surfaces with an autodepositing composition comprising an acidic aqueous coating solution containing dispersed solid resin particles of either an internally stabilized or externally stabilized vinylidene chloride polymer, an exemplary internally stabilized polymer being prepared from vinylidene chloride and a monomeric surfactant which includes an inorganic ionizable group, and an exemplary externally stabilized polymer being prepared from vinylidene chloride and a reactive comonomer, the resulting resin particles having surfactant adsorbed thereon, said autodeposited coatings having extremely good corrosion resistant properties without treatment with a reaction rinse such as a chromium rinse.
