“Industrialnaya” Kronos — acrylic enamel for steel and reinforced concrete bridges

Other anticorrosion materials

A one-component acrylic enamel intended primarily for bridges: it protects steel and reinforced concrete structures against corrosion and carbonation, and conclusions by TsNIIPSK and VNIIZhT have been issued for it. On metal “Industrialnaya” is applied over the sacrificial primer “Tsikron”, on concrete over the primer “Akrilovy”, and it is also used as a protective coat over the sealant “Germokron-Gidro”. The coating is resistant to water, salt solutions and oils, withstands changes from −50 to +60 °C, and its service life is at least 10 years.
