SILRES® BS 2001 is a water-thinnable, solventless emulsion, based on a mixture of silane and siloxane. Ready to use solutions of SILRES® BS 2001 serve as high quality, general purpose water reqellents for impregnating and priming mineral surfaces. SILRES® BS 2001 emulsion contains a stabilized mixture of silane and siloxanes that are designed to hydralyze once applied to the substrate. Alcohol is released and the emulsion is converted into a silicone resin water repellent. SILRES® BS 2001 reduces the capillary absorption of the building which it has penetrated, but does not clog the pores or capillaries. There is therefore little or no impairment of the building material's ability to breathe. The SILRES® BS 2001 is an excellent water repellent for many absorbent mineral substrates such as brick, natural sandstone, concrete, and mineral plasters. It is not as suitable for substrates such as reinforced concrete for bridges and roads, dense natural limestone and marble. Due to its aqueous consistency and storage stability when diluted, SILRES® BS 2001 is ideal for in-plant impregnation of building materials made of clay, aerated concrete, brick and fibrous cement. SILRES® BS 2001 may also serve as a water repellent primer for emulsion paints and plasters, silicone resin emulsion paints and silicone resin plasters as well.


- Good depth of penetration - Resistance to alkalis - Rapid development of water repellency - Provides good adhesion for paints - Water-based and environmentally compatible - Storage stable, even when diluted


The "Best use before end date" of each batch is shown on the Certificate of Analysis. Storage beyond the date specified on the Certificate of Analysis does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
