Sikagard®-705 L

Liquid passive corrosion inhibitor/hydrophobic impregnation for reinforced concrete 

Sikagard®-705 L is a one-component, low viscosity, solvent free, reactive passive corrosion inhibitor for concrete and cementitious substrates based on silane with 99 % active ingredient. Sikagard®-705 L complies with the highest requirements of EN 1504-2 for Hydrophobic Impregnation (penetration depth class II & resistance to freeze and thaw salt stresses).

  • Fast uptake even on dense concrete.
  • Easy to use.
  • Transparent.
  • Excellent and deep penetration.
  • Reduces corrosion even in cracked concrete.
  • Mitigates corrosion rate of depassivated reinforcement bars.
  • Prevents chloride migration to reinforcement bars.
  • Effective against AAR.
  • Can be used on new and corroding, and old, structures.
  • Open to water vapour diffusion.
  • Increases electrical resistivity in concrete.
  • Increases the resistance of concrete to freeze and thaw cycles. 
  • Resistant to sea water.
  • Low VOC content.
  • Complies with Dutch guidelines (RWS NEN-EN 1504-2) on CEM III.
  • Reduces capillary water absorption, protects against mist and splashing on vertical areas.
  • Reduction of absorption of aggressive or deleterious agents dissolved in water (i.e. de-icing salts or chloride from marine environment).
  • Ready to use.
  • Long term durability.
  • Reduced green growth.
