Protectosil CIT

Advanced corrosion inhibitor

Protectosil CIT is an advanced corrosion inhibitor for steel reinforced concrete based on organofunctional silanes. Protectosil CIT dramatically reduces the chloride induced corrosion of steel concrete reinforcement via reaction of active material with the cement phase and the steel surface.

Key Features

  • Low viscous, colorless to yellowish liquid
  • > 98 % active ingredient
  • Solvent free
  • pH of 11
  • Repassivates steel rebars after chloride induced corrosion
  • Highly reactive and resistant to alkaline environment
  • Forms colorless and water vapour permeable impregnations
  • High reduction of water uptake and of chloride uptake
  • Applied undiluted to a concrete surface and is absorbed quickly
  • Equalizes the differences in electrochemical potential between polymer concrete and existing concrete when applied to concrete structures repaired with polymer concrete

Recommended Applications

  • Penetrates deeply into the concrete
  • Suited for old and new structures
  • Suited for every type of steel reinforced concrete
  • Effective in marine environments with high relative humidity and areas where deicer salts are used such as jetties, piers, decks, facades, balconies, walkways, bridge decks, beams, columns
  • Effectively inhibits macrocell (mat-to-mat) and microcell (along rebar) corrosion of steel-reinforced concrete
  • Reduces corrosion in carbonated concrete steel-reinforced structures
