Corrosion Inhibitor

Sika® FerroGard®-901

A liquid concrete admixture based on Sika® FerroGard® Technology for use in reinforced concrete. It acts as a corrosion inhibitor for the steel reinforcement. By using Sika® FerroGard®-901, the life expectancy and durability will be substantially increased.

Sika® FerroGard®-903

Sika® FerroGard®-903 is a corrosion inhibiting impregnation coating for hardened concrete surfaces. It is designed to penetrate the surface and then to diffuse in vapor or liquid form to the steel reinforcing bars embedded in the concrete. Sika® FerroGard®-903 forms a protective layer on the steel surface which inhibits corrosion caused by the presence of chlorides as well as by carbonation of concrete.


How it works

Sika® FerroGard®-903 is a combination of amino alcohols, and organic and inorganic inhibitors that protects both the anodic and cathodic parts of the corrosion cell. This dual action effect dramatically delays the initiation of corrosion and greatly reduces the overall corrosion activity. Sika Sika® FerroGard®-903 protects the embedded steel by depositing a physical barrier in the form of a protective layer on the surface of the steel reinforcement. This barrier inhibits corrosion of the steel.
