| SILRES® BS CREME C is an aqueous, solventless, creamy, silane-based water repellent. It is a highquality specialty product for hydrophobic impregnating of both normal and reinforced concrete. Special features: - excellent penetration
- solventless, aqueous and environmentally compatible
- low volatility
- high resistance to alkalis
- thixotropic and may so be applied without loss of material
Treated concrete will have the following permanent properties:- greatly delays chloride and water absorption by concrete
- no loss in breathability
- improved durability against freeze-thaw de-icing salt stress
- enhanced durability
- provides good adhesion for paints
SILRES® BS CREME C is a unique impregnating agent because it is thixotropic. It has an outstanding ability to impregnate high-quality concrete and reinforced concrete. Unlike conventional liquid products, SILRES® BS CREME C can be applied in just one coat of the desired thickness (at the very most, two coats). The silane active ingredient penetrates the substrate within 30 minutes to several hours, the exact time depending on the porosity and thus quality of the concrete. On reaction with the substrate, it releases ethanol and is converted into a polymeric silicone resin. A creamy layer forms initially, but this then disappears completely. As the active ingredient is the same as in conventional liquid impregnating agents, impregnation with SILRES® BS CREME C does not clog the pores or capillaries, nor does it affect its ability to "breathe". SILRES® BS CREME C is designed to penetrate deeply into concrete so as to afford optimum protection against absorption of water and pollutants as well as freeze / thaw cycles. This effect should not be confused with the "beading" effect imparted by impregnating agents that is often referred to as water repellency. Beading is only a surface effect, and it plays a secondary role in protecting the substrate. Concrete treated with SILRES® BS CREME C has initially only a moderate beading effect, but this increases after the surface has been wetted.Application: SILRES® BS CREME C is recommended particularly for impregnating and priming concrete and reinforced concrete used in building bridges, roads and buildings. In principle, SILRES® BS CREME C may be used on any alkaline substrate that has been treated previously with concentrated or undiluted impregnating agents, such as alkoxysilanes.
