Corrosion is a severe problem affecting the life of any element of the house made of steel or iron. Since paints are devised for protecting metal surfaces, it is broadly believed and also misunderstood that all oil based paints are anti-corrosive paints. It is not a correct version. All oil-based paints are not anti-corrosive paints. They are merely decorative paints which protect the metal surface partially against the climatic corrosion but fail to stand against the drastic corrosion caused by various industrial chemicals & gases.
Corrosion resistant coatings protect metal components against degradation due to moisture, salt spray, oxidation or exposure to a variety of environmental or industrial chemicals. The anticorrosive paints impede or obstruct the corrosion by reducing the direct access of air and water to the metal. Anti corrosion coating allows added protection of metal surfaces and acts as a barrier to inhibit the contact between chemical compounds or corrosive materials. A wide variety of anti corrosion coatings is available. These types of anti corrosion coating are mostly applied on iron or steel products.
Anti corrosive paint is a composition of corrosion resistant pigments such as zinc chromate, lead chromate, zinc oxide, zinc dust, zinc chromate, or red lead. Linseed oil is used as a binder in the anti corrosive paint.
