| SILRES® BS 17040 is a water-thinnable, solventless silane emulsion. SILRES® BS 17040 serves as highquality water repellent for impregnating and priming of alkaline mineral surfaces. Moreover SILRES® BS 17040 can be used as water resisting admixtures for non-load bearing manufactured concrete products. Special features: SILRES® BS 17040 is characterised by: - good depth of penetration
- dilutable with water, and free of solvents
- low volatility
- high resistance to alkalis
- stable in storage, even when diluted treated concrete will have the following permanent properties:
- dramatic reduction in chloride and water absorption
- no loss in breathability
- improved durability against freeze-thaw de-icing salt stress
- enhanced durability
- provides good adhesion for paints
In the construction material, SILRES® BS 17040 reacts with atmospheric moisture and / or the water in the building material’s pores, eliminating alcohol. The active thus substance formed greatly reduces the concrete’s absorbency in the active zone (penetration depth after post treatment), but without blocking any pores or capillaries. The impregnated building material retains very high water-vapor permeability. Application: SILRES® BS 17040 is recommended for the hydrophobic impregnation and priming of concrete and reinforced concrete in road, bridge and building construction as well as water resisting admixtures for non-load bearing manufactured concrete products. For the hydrophobic impregnation of high-grade, load bearing concrete SILRES® BS 17040 must be used undiluted, as the product has been approved in that concentration according to EN 1504-2.
