Sikagard®-705 L
Silane based reactive water repellent impregnation.
Sikagard®-705 L is a one-component low viscosity, solvent free liquid, reactive impregnation 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).
- Excellent penetration
- Fast uptake even on dense concrete
- 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. de-icing salts or chloride from marine environment)
- No change in water vapour permeability
- Long term efficiency, deep penetration
- Increases the resistance of concrete to freeze and thaw cycles and de-icing salts
- Reduce corrosion even in cracked concrete
- Retard corrosion initiation by reducing the available humidity at reinforcement bars level
- Mitigate corrosion by preventing further chloride to migrate to reinforcement bars
- Comply with Dutch guidelines (RWS NEN-EN 1504-2) on CEM III
- Resistant to sea water
- Low VOC content
- Ready to use
