Tile adhesive and grout mortar

In tile adhesives and grout mortars, VINNAPAS® polymer binders optimize mechanical properties such as adhesion, flexibility, and cohesive strength. At the same time, they make installation easier, allowing for the thin-bed technique. SILRES® POWDER additives also provide reliable protection against moisture.

Sealing systems

Thanks to polymer modification with VINNAPAS® binders, single-component (1K) and two-component (2K) sealing systems offer excellent adhesive strength, flexibility, and durability – even under hydrostatic pressure.

Self-leveling flooring compound

VINNAPAS® polymer binders are suitable for the formulation of single-component (1K) self-leveling flooring compound and screeds. They optimize flow and leveling properties, increase adhesive strength and abrasion resistance, while minimizing bubble formation.

Surface treatment

Silane-terminated SILRES® BS products and siliconized acrylic-based PRIMIS® dispersions act as film-forming impregnations that reliably protect the open-pored structure of concrete or screed floors from contamination.

Facade impregnation

Water-repellent impregnation with SILRES® BS provides long-lasting protection for mineral-based building materials against damage caused by moisture penetration. It reduces capillary water absorption while preserving the water vapor permeability and breathability of the material.

Infrastructure and concrete modification

ETONIS® polymer binders increase the longevity of concrete tunneling and are ideal for sustainable and cost-effective soil stabilization in road construction. Vinyl acetate-ethylene (VAE) dispersible powders improve the adhesion, flexibility, and strength of repair mortars. SILRES® BS water-repellent agents reduce capillary water absorption in concrete.

Insulating materials

SILRES® BS forms a hydrophobic silicone resin network in mineral insulation materials, which reduces capillary water absorption while maintaining water vapor permeability. GENIOSIL® products act as adhesion promoters in bonded mineral wool, ensuring optimal adhesive strength between the inorganic fibers and the organic binder. This effectively protects treated materials from harm due to moisture.

VINNAPAS® polymer binders improve the adhesive strength and flexibility of mortars, plasters, and fillers in gypsum and fiber-cement panels. SILRES® BS silicones are ideal for rendering these building materials water-repellent.

VINNAPAS® and ETONIS® polymer binders offer excellent compatibility with cement and optimize the mechanical properties of cement-based dry mortars. SILRES® BS silicone additives improve the storage stability of cement and increase the water-repellent properties of mortar and concrete.

Solvent-free SILRES® BS products, which are silane/siloxane-based, are applied directly into the masonry through boreholes. There, a chemical reaction causes them to form a reliable horizontal barrier that effectively stops rising damp.

VINNAPAS® dispersions used in primers and adhesion promoters help ensure the long-term stability of multi-layer systems. They ensure excellent adhesion to a wide variety of substrates and good penetration into the surface.

SILRES® BS silicone products provide long-lasting water-repellent impregnation of ceramic construction materials. They reliably protect against water, salts, and contamination while maintaining water vapor permeability.

Sustainability is feasible: facades

First impressions count – and that goes for buildings too. But it is not only the facade that determines whether a building appeals to us aesthetically. In many cases, its appeal hinges on how sustainable it is too. Because facades offer fantastic opportunities to put sustainable construction into effect.
