Abstract: The invention relates to a method for applying a corrosion-resistant coating to a metal part by immersing/withdrawing said part in/from an aqueous paint bath. The invention is characterized in that the aqueous paint bath includes water, a binder and cellulose microfibrils, and in that the coated metal part is subjected to vibrations when removed from the bath. The invention also relates to an aqueous coating composition including water, a binder, metal particles and CMNFs. The invention also relates to a corrosion-resistant coating for metal parts that is characterized in that it is obtained by the method according to the invention, the coating layer subsequently being subjected to a curing operation preferably at a temperature of between 70° C. and 350° C. Lastly, the invention relates to a metal part provided with a corrosion-resistant coating according to the invention.
Abstract: Anticorrosion coating compositions for metallic parts based on particulate metal in aqueous dispersion are described. The compositions include an organic titanate or zirconate compatible in aqueous phase or in organic phase, an optional silane-based binder, and water. Also described are methods of forming anticorrosion coatings for metallic parts obtained from the noted coating compositions as well as a metallic substrate provided with the anticorrosion coating. The anticorrosion coatings exhibit excellent corrosion resistance upon baking at temperatures greater than 180° C. and up to 350° C.
