InvoCor RCI Migrating Corrosion Inhibitors

  • InvoCor RCI’s are a family of migratory corrosion inhibitors for the protection concrete reinforcing steel. They are typically used in silane based protective barrier coatings. They are based on a synergistic mixture of amine carboxylates and vapor phase inhibitors. This synergistic mixture has been designed with a high degree of water solubility, providing excellent inhibitor transport (migration) through the concrete.
  • InvoCor RCI’s have a strong affinity for absorption onto the surface of the reinforcing rebar in concrete and demonstrate superior inhibiting properties even in the presence of high chloride ion concentrations

  • The products are supplied in three different product variations:
    1. InvoCor RCI-1360: This variation is cut in methanol so that it is easily incorporated and compatible with most commercially available silanes.
    2. InvoCor RCI-1370: This product variation is water produced in water and is compatible in water-based silane modifications.
    3. InvoCor RCI-1380: This product variation is to be used as a concrete pretreatment prior to silane application. It has been modified with a synergistic blend of wetting agents to aid the initial concrete penetration.
  • Typical loading level recommendations are 5% for InvoCor RCI-1360 and RCI-1370 on total formulation weight. For concrete pretreatment, the loading of InvoCor RCI-1380 should be 33% to 50% mixture in water.
