Products in Building Materials: Water Repellent

SILRES® BS 1360 is a nonionic, solvent-free, water-dilutable emulsion of a reactive polysiloxane. It can be added in undiluted form to aqueous masonry protection agents either during or after their production. Similar to SILRES® BS 1346, SILRES® BS 1360 is used undiluted as a hydrophobizing additive for aqueous masonry paints. Its primary functions are to enhance water repellency, water resistance, water vapor permeability, processability, and anti-blocking properties.

SILRES® BS 5133 is an aqueous and water-dilutable emulsion of reactive polydimethylsiloxane (PDMS). It is specifically formulated to provide water repellency to thermal insulation materials made of glass or stone mineral wool that are bound with organic binder systems. SILRES® BS 5133 has been carefully developed and optimized to ensure compatibility with binders based on carbohydrates, allowing for effective integration into various insulation materials and systems.

SILRES® BS 1705 is a high-quality water-thinnable emulsion that is solvent-free and based on a mixture of silane and siloxane compounds. It is specifically designed to act as a specialty water repellent for impregnating cement-based products, including fiber cement. By impregnating cement-based materials, such as fiber cement, with SILRES® BS 1705, their water repellency is significantly enhanced, providing long-lasting protection against water absorption and related problems. This makes SILRES® BS 1705 an excellent choice for improving the durability and performance of cement-based products in various applications.

SILRES® BS 1702 is a solvent-free mixture of silane and siloxane that can be applied either in undiluted form or diluted with organic solvents. It is specifically designed as a high-quality specialty water repellent for impregnating fiber cement. When applied to fiber cement, SILRES® BS 1702 acts as an effective water repellent, helping to protect the material from moisture absorption and potential damage caused by water.

SILRES® BS 2001 is a water-thinnable, solventless emulsion based on a mixture of silane and siloxane. It is a ready-to-use solution that serves as a high-quality water repellent for impregnating and priming mineral surfaces. After application, the emulsion undergoes hydrolysis, releasing alcohol and converting into a silicone resin.

SILRES® BS 1703 SQ (000096394) is also primarily intended for in-plant water-repellent treatment of fiber-reinforced cement products, such as fiber-cement boards. It exhibits a higher flash point and increased storage stability compared to SILRES® BS 1703. While it may have a slightly opalescent appearance with a slight yellowish discoloration, it does not affect the excellent performance of the product.

SILRES® BS 94 is a highly effective, anhydrous silicone product based on polymethylhydrogensiloxane. It is specifically designed for the water-repellent treatment of plaster elements and plasterboard or wallboard surfaces. When applied to plaster elements or plasterboard, SILRES® BS 94 acts as a water-repellent agent, helping to protect these materials from water absorption. By reducing water uptake, it can enhance the durability and lifespan of plaster surfaces. The use of SILRES® BS 94 can help prevent water-related issues such as moisture damage, staining, and deterioration of plaster elements and plasterboard. It provides an effective barrier against water penetration while maintaining the visual appearance and structural integrity of the treated surfaces.

SILRES® BS Powder G is a water repellent in powder form for gypsum and construction material mixes containing gypsum. It must be thoroughly mixed with the gypsum before water is added. Good water repellency is obtained by adding 0.5 to 2.0% by weight of powder, based on the dry weight of the gypsum. The exact amount depends on the type of gypsum and the quantity of mixing water.

SILRES® BS 1703 SQ (000010587) is specifically designed for the in-plant water-repellent treatment of fiber-reinforced cement products, including fiber-cement boards. Its main purpose is to greatly reduce the capillary water absorption of these construction materials once they have set and reached equilibrium moisture. The use of SILRES® BS 1703 SQ provides enhanced protection against water damage, contributing to the longevity and quality of fiber-reinforced cement products.

SILRES® BS 1346 is a nonionic, solvent-free, water-dilutable emulsion of a reactive polysiloxane. It is used in its undiluted form as a hydrophobizing additive for aqueous masonry paints or plasters. Its purpose is to increase water repellency, water resistance, and water vapor permeability while also enhancing processability and antiblocking properties.

VINNAPAS® 8034 H is a very strong hydrophobic dispersible polymer powder for dry mix mortars, specifically suited for tile grouts, renders, plasters, and skim coats. It is based on a flexible terpolymer of vinyl chloride, ethylene, and vinyl laurate. VINNAPAS® 8034 H belongs to the product class VINNAPAS® H, which means that it provides a remarkable hydrophobic effect in addition to adhesion properties.

VARIPHOB® AC 5002 is a silicone-based hydrophobic powder used as a water-repelling agent for the protection of mineral-based construction materials. This product is used for cement-based systems, such as bathrooms, swimming pools, showers, saunas, wellness areas.

VARIPHOB® AC 5002 is particularly well-suited for construction materials such as:

• Mineral mortars / Grouts
• Plasters
• Renders
• Concrete
• Joint fillers
• Sealing mortars
• Levelling compounds
• Skim Coats
• Stucco

It increases durability by reducing water absorption, and increases surface hydrophobicity of the materials used. This product also provides full breathability so that water vapor can easily evaporate.

SILRES® BS 1340 is a nonionic, solvent-free, waterborne emulsion of a reactive polysiloxane. It is specifically used in the formulation of water-resistant coatings. SILRES® BS 1340 can be directly incorporated, without dilution, into waterborne masonry paints and plasters either during or after their production.
