Evonik Protectosil CIT is an advanced, surface-applied treatment designed to significantly reduce corrosion in steel-reinforced concrete structures. By penetrating the concrete, Protectosil CIT delivers an organofunctional silane molecule that effectively inhibits the electrochemical corrosion process between rebar, chloride ions, oxygen, and moisture.
Product Features and Benefits:
– Corrosion Inhibition: Dramatically lowers the rate of chloride-ion-induced and carbonation-related corrosion in reinforced concrete.
– Deep Penetration: Chemically bonds with steel, cement paste, and siliceous materials within the concrete to provide robust protection.
– Surface Integrity: Does not alter the appearance or friction of the substrate’s surface.
– Environment Suitability: Ideal for use in marine environments and areas prone to high humidity or where deicing salts are common.
– Wide Application Range: Suitable for a variety of concrete structures including parking decks, bridges, walkways, and marine piers.
Advantages:
– High Efficiency: Protectosil CIT significantly reduces both macrocell and microcell corrosion currents, protecting against deep-set and surface-level corrosion.
– Compatibility: Works seamlessly with both new and repaired structures, including those incorporating polymer concrete, without affecting the electrochemical potential.
– User-Friendly: Easy to apply and dries quickly without affecting the vapor permeability of the concrete.
– Comprehensive Protection: Prevents the ingress of additional chlorides and is effective even in heavily contaminated or carbonated concrete.
Application Instructions:
For optimal results, the concrete must be thoroughly cleaned to ensure full penetration and effectiveness. Protectosil CIT can be applied directly to cleaned rebar before placing repair material and does not impede the adhesion of most sealants used in concrete repairs.
Evonik Protectosil CIT is an essential solution for extending the lifespan of concrete structures by addressing the root causes of corrosion with cutting-edge chemical technology.
