Polymeric binders and additives for tile adhesives and grout mortars
Polymer-modified tile adhesives can also be used in combination with the thin-bed technique for installing even large-format tiles securely and efficiently.
We expect a lot from tile adhesives and grout mortars: a huge array of tile materials and formats, different substrates and stress between the substrate and the tiles quickly push classic formulations to their limit.
In tile adhesives and grout mortars, VINNAPAS® polymeric binders optimize mechanical properties such as adhesion, flexibility and cohesive strength. At the same time, they make materials easier to work with and open the door to thin-bed technology – today’s most advanced tile installation technique. Plus, SILRES® POWDER additives based on silanes and silicones offer reliable protection from moisture.
Modern tile adhesives and grout mortars: challenges and solutions
Typical challenges:
This video will take you on a quick 3-minute journey deep inside a cementitious tile adhesive, showing you how polymeric binders improve the adhesion, flexibility and impact resistance of the cement matrix.
Our solution:
VINNAPAS® polymeric binders form a polymer network within the cement matrix, improving the adhesion, flexibility and cohesion of tile adhesives and grout mortars. Lasting adhesion is the result – even on critical substrates like gypsum plasterboard, wood or old tiles. The improved flexibility prevents cracking due to stress between the substrate and the tiles. And extended open time makes the materials easier to work with. VINNAPAS® polymeric binders are available as either dispersible polymer powders or as polymer dispersions. Feel free to contact us if you’d like to hear more about polymer dispersions for 2K cementitious tile adhesives.
SILRES® POWDER additives based on silanes and silicones do an effective job of hydrophobizing surfaces and material blends. By forming a water-repellent silicone network that reduces moisture absorption, they deliver long-lasting joints that will look good for years to come.
Dispersible polymer powders for 1K cementitious tile adhesives
One-component (1K) cementitious tile adhesives consist of a polymer-modified dry-mix mortar that can simply be blended with water at the installation site. VINNAPAS® dispersible polymer powders improve their adhesion and flexibility. 1K cementitious tile adhesives are suitable for installing fully vitrified tiles on tricky substrates while delivering the ideal price/performance ratio.

The benefits:
VINNAPAS® improves flexibility and therefore longevity.
Applications:
Side note: Tile adhesives can be broken down into S1 and S2 classes to indicate their flexibility: S1 is a flexible adhesive, whereas S2 is highly flexible. As shown in the diagram entitled “Deformability of cementitious tile adhesives at 23 °C,” the S1 class corresponds to values of ≥ 2.5 mm, while S2 corresponds to ≥ 5.0 mm.
Dispersions for ready-to-use 1K tile adhesives
Ready-to-use 1-component tile adhesives can be applied directly, with no need for mixing at the installation site. VINNAPAS® polymer dispersions improve both the adhesive and cohesive strength of 1K systems, as well as their flexibility, making it possible to bond a wide range of tiles on almost any surface, such as old tiles, wood or plaster.

Polymer dispersions for formulating ready-to-use 1-component (1K) tile adhesives
The benefits:
Shear strength – tested after storage and under various conditions – is the most decisive performance criterion for class D2 ready-to-use ceramic tile adhesives. Unlike standard styrene-acrylic dispersions, VINNAPAS® silanized styrene-acrylic dispersions can be used for formulating class D2 ready-to-use ceramic tile adhesives.
Applications:
Polymer binders for grout mortars
Grout mortars containing VINNAPAS® lend tiled areas long-term protection from moisture, dirt and mechanical stress. These grouts are wear resistant, water repellent and flexible – for visually attractive surfaces that last.

Applications
Silicone powder additives for grout mortars
Incorporating SILRES® POWDER additives into dry-mix formulations improves the long-lasting water repellency, reduces the water absorption and increases the stain resistance of the finished product. These products are compatible with a broad range of dry additives and remain stable in alkaline formulations.
Our SILRES® POWDER additive portfolio includes silanes and functional silane-based products that are manufactured using two different technologies. In SILRES® POWDER A, the active agent is located on the surface of an inorganic carrier – in SILRES® POWDER D and SILRES® POWDER E, however, it is encapsulated.

DownloadFAQs on tile adhesives and grout mortars
Why modify tile adhesives and grout mortars with VINNAPAS®?
VINNAPAS® polymer dispersions and dispersible polymer powders improve tensile adhesive strength, flexibility and cohesion in tile adhesives and grout mortars. These products enable a lasting bond between a tile and its substrate, prevent cracks from forming and extend the service life of flooring.
What applications lend themselves to polymer-modified tile adhesives?
Tile adhesives modified with VINNAPAS® are suitable for natural and artificial stone, large-format tiles, damp interiors, kitchens and exterior surfaces. They form a reliable bond on mineral and non-mineral substrates, such as concrete, gypsum plasterboard and old tiles.
How do SILRES® POWDER additives protect joints from moisture?
Based on silane and silicone, hydrophobic SILRES® POWDER additives form a water-repellent network within the mortar matrix as a whole, preventing moisture ingress – and yielding joints that resist staining, last a long time and are color fast.
What are the advantages of incorporating hydrophobic additives in grout mortars?
Hydrophobic additives like SILRES® POWDER prevent water absorption and blooming, make grout mortars better able to withstand abrasion and extend their service life with no negative impact on breathability or strength.
