Sikagard®-740 W

Silane based reactive water repellent penetrating sealer

Sikagard®-740 W is a one part low viscosity, reactive impregnation for concrete and cementitious substrates based on concentrated Silane emulsion. Sikagard®-740 W complies with the requirements of NCHRP Report 244 Series II & IV. Sikagard®-740 W is classified under the ALBERTA infrastructure and transportation specifications. Sikagard®-740 W complies with the highest requirements of EN 1504-2 for hydrophobic Impregnation (penetration depth class II & resistance to freeze-thaw cycles and chloride ion penetration).

  • Reduces capillary water absorption, protection against driving rain and splashing on vertical areas
  • Reduction of absorption of aggressive or deleterious agents dissolved in water (i.e. chlorides)
  • No change in water vapour permeability
  • Increases the resistance of concrete to freeze and thaw cycles and de-icing salts
  • Water based emulsion, Low VOC
  • Resistant to sea water
  • Ready to use
