Antirust paint

Anti-rust paint is a coating that protects metal surfaces from chemical or electrochemical corrosion of the atmosphere, sea water, and the like. Mainly divided into two major categories of physical and chemical anti-rust paint. The former relies on the proper cooperation of pigments and paints to form a dense paint film to prevent the intrusion of corrosive substances, such as iron red, aluminum powder, graphite antirust paint, etc.; the latter relies on the chemical rust inhibitor effect of anti-rust pigments, such as red Dan, zinc yellow antirust paint, etc. Used for rust prevention of metals such as bridges, ships and pipelines.
