WACKER Introduces VINNAPAS 8620 E, a Dispersible Polymer Powder for Tile Adhesives

WACKER has developed a novel dispersible polymer powder for modifying cementitious and gypsum-based dry-mix mortars. VINNAPAS 8620 E is based on a terpolymer of vinyl chloride, vinyl acetate and ethylene, and is ideal for the formulation of high-quality, low-emission tile adhesives. In the end product, the new dispersible polymer powder ensures a long open time and enhanced flexibility combined with excellent tensile adhesion strength, even after water or freeze/thaw conditions. With VINNAPAS 8620 E in the formulation, it is thus even possible to reliably bond.

Lab test: tile adhesives formulated with the new VINNAPAS 8620 E dispersible polymer powder offer a long open time and enhanced flexibility combined with excellent tensile adhesive strength, even after conditioning in water.

The new VINNAPAS 8620 E is a dispersible polymer powder based on a novel vinyl chloride-vinyl acetate-ethylene-terpolymer for modifying modern cementitious and gypsum-based dry-mix mortars, particularly for tile adhesives. VINNAPAS 8620 E ensures that tile adhesives adhere excellently to a broad range of different surfaces, including difficult ones such as fired tiles with high densities and natural-stone products ? even after heat, water or freeze/thaw conditions. The dispersible polymer powder was specifically developed for the formulation of sophisticated tile adhesives of categories C2E or C2ES1 and C2ES2 as per EN 12004 that feature an extended open time and high flexibility. It thus offers users additional formulation reliability.

Alongside exceptional product and processing properties, VINNAPAS 8620 E also exhibits good environmental compatibility, because the product is free of plasticizing additives and thus makes it possible to formulate low-emission tile adhesives.
