Description Silane based reactive water repellent impregnation. Sikagard®-705 L is a one-component low viscosity, solvent free, 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). Suitable for use in hot and tropical climatic conditions. Excellent penetration Fast uptake even on dense concrete Economic and easy to use 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 Usage Sikagard®-705 L is used as water-repellent impregnation (hydrophobic treatment) for absorbent substrates such as concrete in civil engineering or building concrete structures subjected to heavy stress due to freeze and thaw cycles and de-icing salts and chloride attack in marine environment 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) Advantages 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 Packaging 25 L pail and 200 L drum. Colour Water like liquid, colourless.
