Description

[0001] technical field [0002] The application belongs to the field of coatings, in particular to a coating for anti-corrosion copper. [0003] Background technique [0004] Anti-corrosion coatings, generally divided into conventional anti-corrosion coatings and heavy-duty anti-corrosion coatings, are an indispensable coating in paint coatings. Conventional anti-corrosion coatings play an anti-corrosion effect on metals under normal conditions and protect the service life of non-ferrous metals; A type of anti-corrosion coating that achieves a longer protection period than conventional anti-corrosion coatings. [0005] Anti-corrosion coatings have become an important new force in the field of coatings. Anti-corrosion coatings are playing an increasingly important role, and their development prospects are promising. However, traditional products are gradually improved, and new products are continuously developed and released. To adapt to the new standards and requirements ...
