A surface-applied clear liquid that penetrates concrete and provides an organofunctional molecule to inhibit the electrochemical corrosion process between the rebar and the chloride ions, and oxygen and moisture within the concrete.
Protectosil CIT:- Dramatically reduces the chloride-ion-induced corrosion rate of concrete steel reinforcement
- Reduces corrosion in carbonated concrete steel reinforced structures
- Is an easy-to-use treatment that penetrates the concrete and chemically bonds with steel, cement paste and other siliceous material
- Will not discolor or change the substrate’s surface appearance or surface friction
- Effectively inhibits macrocell (mat-to-mat) and microcell (along rebar) corrosion of steel-reinforced concrete
- Mitigates corrosion of rebar even in structures subjected to an environment with high relative humidity
- Repels additional water and chloride ions
APPROPRIATE APPLICATIONS:- Steel-reinforced cast-in-place, precast, post tension, GFRC, prestressed or other steel-reinforced concrete
- Parking decks, facades, balconies, walkways, piers, bridge decks, beams, columns and other steel-reinforced concrete structures
- Marine environments with high relative humidity and areas where deicer salts are used
ADVANTAGES: Protectosil CIT dramatically decreases both mat-to-mat (>90%) and microcell (>87%) corrosion currents. Protectosil CIT works on the molecular level to effectively inhibit the electrochemical interaction of the corrosion process. This advanced inhibiting action makes Protectosil CIT the best choice for difficult applications. Applied to concrete structures repaired with polymer concrete, Protectosil CIT can equalize the differences in electrochemical potential between the polymer concrete and the existing concrete. The product:- Inhibits corrosion of carbon and galvanized steel rebar
- Is effective in both marine and high-humidity environments
- Is easy to apply
- Is effective in heavily chloride-contaminated concrete
- Is effective in carbonated concrete
- Complies with VOC regulations
- Is vapor permeable
- Dries quickly
- Prevents ingress of additional chlorides
