Sika® FerroGard®-903 Plus – Active corrosion inhibitor for reinforced concrete
Sika® FerroGard®-903 Plus is a surface applied active corrosion inhibitor, based on organic compounds, designed for use as an impregnation of steel reinforced concrete. It 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.
Recommended Uses
- For the corrosion protection of steel reinforced concrete structures above and below the ground.
- As a corrosion control treatment for undamaged reinforced concrete where reinforcing steel is corroding, or is at risk from corrosion due to the effects of carbonated or chloride contaminated concrete.
- Sika® FerroGard®-903 Plus is especially suitable for extending the service life of aesthetically valuable fair-faced concrete surfaces such as historic structures.
