Description

Sikagard®-740 W is a one-component low viscosity, reactive impregnation for concrete and cementitious substrates based on concentrated Silane emulsion. Sikagard®-740 W complies with the requirements of EN 1504-2 for hydrophobic Impregnation (penetration depth class I & resistance to freeze and thaw salt stresses).

Uses

Sikagard®-740 W is used as water-repellent impregnation (hydrophobic treatment) for absorbent substrates such as concrete in civil engineering or building concrete structures in both vertical and horizontal traffic area:

  • Suitable for protection against ingress (Principle 1, method 1.1 of EN 1504-9)
  • Suitable for moisture control (Principle 2, method 2.1 of EN 1504-9)
  • Suitable for increasing the resistivity (Principle 8, method 8.1 of EN 1504-9)

Benefits

  • Good penetration
  • Economic and easy to use
  • 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
