Description
Sika® FerroGard®-903+ is a surface applied mixed corrosion inhibitor, designed for use as an impregnation of steel reinforced concrete and is an improved formulation of the original Sika® FerroGard®-903.
Sika® FerroGard®-903+ is based on organic compounds. Sika® FerroGard®-903+ penetrates the concrete and forms a protective monomolecular layer on the surface of the reinforcing steel.
Protection with Sika® FerroGard®-903+ delays both the start of corrosion and reduces the corrosion rate. Corrosion protection with Sika® FerroGard®-903+ increases the service and maintenance life cycles by up to 20 years when used as a part of a complete Sika Concrete Repair and Protection System.
