Sika® FerroGard®-903 Plus

Sika® FerroGard®-903 Plus is a surface applied mixed corrosion inhibitor, designed for use as an impregnation of steel reinforced concrete.

Sika® FerroGard®-903 Plus is based on organic compounds. Sika® FerroGard®-903 Plus penetrates the concrete and forms a protective monomolecular layer on the surface of the reinforcing steel. Sika® FerroGard®-903 Plus both delays the start of corrosion and reduces the corrosion rate. Corrosion protection with Sika® FerroGard®-903 Plus increases the service and maintenance life cycles by up to 15 years when used as a part of a complete Sika Concrete Repair and Protection System.
