Anti-corrosion coatings are an indispensable coating in paints and coatings. In addition to the commonalities of general coatings, they also play an anti-corrosion role and protect the service life of non-ferrous metals. The anti-corrosion principle of anti-corrosion coatings is simply to prevent oxygen or other corrosive media from preparing oxide contact.

Anti-corrosion coating is an indispensable coating in paint coatings. In addition to the commonalities of general coatings, it also plays an anti-corrosion role and protects the service life of non-ferrous metals. The anti-corrosion principle of anti-corrosion coatings is simply to prevent oxygen or other corrosive media from preparing for oxide contact. Anti-corrosion coatings are an essential coating in paint coatings. In addition to the commonalities of general coatings, it also plays an anti-corrosion role and protects the service life of non-ferrous metals. Function: Corrosion inhibition and passivation: In addition to containing film-forming substances in anti-corrosion coatings, various pigments are also added as needed. For example, adding eight alkaline is expected. When moisture or sexual substances penetrate through the pancreas. The alkaline pigment will neutralize these substances, keep the coating film and the metal interface alkaline, and passivate the metal. This shows the anti-corrosion effect, and some pigments can also react with the fats in the film-forming substances to form metal soaps to act as corrosion inhibitors. For example, adding eight soluble pigments (chromium salts such as chromium zinc: pigments), these pigments are in contact with water, and chromium ions are dissolved.
