Anti corrosion coatings are generally divided into conventional anti-corrosion coatings and heavy-duty anti-corrosion coatings, and are an essential type of coating in paint and coatings. Conventional anti-corrosion coatings play a role in preventing corrosion of metals and protecting the service life of non-ferrous metals under general conditions; Heavy duty anti-corrosion coatings refer to a type of anti-corrosion coating that can be applied in relatively harsh corrosive environments and has a longer protection period than conventional anti-corrosion coatings.
