Paint anti-corrosion refers to the ability of paint to resist the electrochemical reaction with its surroundings. It protects the substrate from rust, UV damage, moisture, and free radicals. Corrosion is often linked with metal and steel substrates. It also damages the non-metallic materials like polymers, ceramics, and plaster. Anti-corrosion paint contains rust-resistant pigments, binders, and additives. Homeowners rely on oil-based paints to protect the metal and steel substrates from oxidation. All oil-based (alkyd, enamel) paints are not rust-resistant, as it depends on the type of pigment used in paint formulation. Anti-corrosion paints act as a protective barrier to resist moisture and air from trapping in the paint surface. They are breathable paints that allow the air to escape. Anti-rust resistant paints reduce the future expense of frequent repainting. It is used to paint decorative items, building exteriors, and industrial equipment.
