Protection of metalwork from corrosion by polyurethane coatings

An overview of the properties, benefits and applications of polyurethane coatings for corrosion protection of metals. Polyurethanes of various structures with different technological, physiochemical and anti-corrosion properties can be manufactured depending on the initial components and reaction conditions. Properties can be varied within wide limits. Materials are classified as either one-component or two-component. Surface preparation requirements and technology are briefly outlined. Russia has since stopped domestic production, but uses materials from German company Steelpaint. This company has considerable experience in a range of applications and climatic zones worldwide. One-component coatings from Steelpaint have been used for anti-corrosion works on metal components of the Riga and Kegum hydroelectric power stations in Latvia.
