Description :

Independently verified, dual-phase, surface-applied corrosion inhibitor

Sikagard®-8500 CI is a one-component, ready to use, low viscosity, clear liquid that combines the power of
a 100% active penetrating corrosion inhibitor and a latent-phase corrosion inhibitor to mitigate electrochemical
corrosion of reinforcing steel in new or aged concrete. Sikagard®-8500 CI uniquely combines the primary reactive penetrant with a second, latent-phase corrosion inhibitor. This latent-phase inhibitor activates when
the concrete cracks, migrating to the reinforcing steel to provide an extra level of protection when it is most
needed.

Uses :

Sikagard®-8500 CI is sprayed directly onto the surface of steel reinforced concrete structures and buildings.
It is equally suited to cast in situ, precast, post tensioned, pre-stressed, GFRC or other steel reinforced
concrete. Sikagard®-8500 CI is primarily used for horizontal applications (i.e. decks) where saturation can be readily achieved. The Product can be used as part of an overall repair strategy using Sika® Concrete Repair Systems to mitigate corrosion rates within the balance of the structure and significantly reduce the possibility of ‘ring anode’ or ‘halo effect’ induced spalling later. Equally Sikagard®-8500 CI can be used as a cost-effective preventative measure before the onset of corrosion induced problems occur.

Characteristics/Advantges :

• 100% active ingredients. No diluents or fillers.
• Easy to apply and quick-drying for fast installation.
• Provides water repellent surface to prevent penetration of moisture and chlorides.
• Reduces corrosion due to the ‘ring anode’ or ‘halo effect’.
• Suitable for use in new construction and repair applications.
• Effective in chloride-contaminated and carbonated concrete to significantly slow down the rate of corrosion.
• Latent-phase corrosion inhibitor activates if concrete cracks or if moisture penetrates the concrete, providing extended protection when it is most needed.
• Vapour-permeable, to prevent moisture entrapment. Effective in high humidity environments to mitigate
  corrosion of reinforcing steel.
• Easy to apply surface treatment that penetrates into the concrete to bond with steel and the concrete
  matrix to inhibit macrocell (mat-to-mat) and microcell (along rebar) corrosion of steel reinforced concrete.
• Can be covered with most types of subsequent coatings, thereby reducing downstream labour costs
  compared with many other corrosion inhibitors.
