VINNAPAS® 8620

Terpolymer of vinyl chloride, vinyl acetate and ethylene. It is a dispersible polymer powder in the medium Tg range. Can modify cementitious and gypsum-based dry-mix mortars which show improved deformability and abrasion resistance. Shows no effect on rheological properties. Being free from plasticizing additives, it exhibits good environmental compatibility, thus making it possible to formulate low-emission tile adhesives. 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. Offers long open time, enhanced flexibility and excellent tensile adhesion strength.
