process of applying an anti-corrosion coating on a metal part, aqueous coating composition, anti-corrosion coating of metal parts and coated metal part

摘要

The invention relates to a method of applying an anti-corrosion coating to a metal part by dipping / removing said part in an aqueous paint bath, characterized in that the aqueous paint bath comprises water, a binder and cellulose microfibrils. and wherein at the outlet of the bath the coated metal part is subjected to vibration. The invention also relates to an aqueous coating composition comprising water, a binder, metal particles and mnfc. The invention also relates to an anti-corrosion coating of metal parts, characterized in that it is obtained by the process according to the invention, the coating layer then undergoing a baking operation preferably conducted at a temperature comprised of between 70 ° C and 350 ° C. Finally, the invention relates to a metal part equipped with an anti-corrosion coating according to the invention.
