$VINNAPAS<sup>®</sup> eco 8620 E

VINNAPAS® eco 8620 E is a multi-purpose dispersible polymer powder for dry mix mortars, specifically suited for tile adhesives. It is based on a flexible copolymer of vinylacetate, ethylene and vinylchloride and belongs to the product class VINNAPAS® E which means that it provides enhanced properties, like extended open time and excellent adhesion after water immersion.

The technical properties of VINNAPAS® eco 8620 E and VINNAPAS® 8620 E are identical.

VINNAPAS® eco 8620 E is a fossil resources saving product. With the purchase of this product, 100 % of the fossil-based raw materials required for manufacturing of this product are replaced by sustainably certified biomass. The Substitution is based on the REDcert² biomass balance approach audited by TÜV Nord.


  • VINNAPAS® eco 8620 E is a dispersible polymer powder based on a new generation of terpolymer composed of vinyl acetate, vinyl chloride and ethylene.
  • VINNAPAS® eco 8620 E is a polymeric binder and is ideal for modifying cementitious and gypsum-based drymix mortars, especially tile adhesives.
  • It provides very good workability, improved adhesion, flexibility, deformability and abrasion resistance.
  • VINNAPAS® eco 8620 E contains a fine mineral filler as an antiblocking agent.
  • It is produced without the use of organic solvents, plasticizers and film-forming agents.
  • VINNAPAS® eco 8620 E has no effect on rheological properties and is a polymer powder in the medium Tg range. It is suitable for formulating high-quality, low-emissions flexible tile adhesive that feature excellent tensile adhesion strength, especially after water immersion and exposure to freeze/thaw cycles.

For typical application fields of VINNAPAS® eco 8620 E, refer to the section "application". Please discuss additional applications with your WACKER customer representative.


For the production of ready-mixed dry mortars, such as adhesives and patching compounds, blend VINNAPAS® eco 8620 E with the other dry ingredients in appropriate equipment. Temperatures should not be allowed to rise excessively during mixing because otherwise the dispersible polymer powder could agglomerate by virtue of its thermoplastic properties. The mortar is prepared for use by adding the recommended amount of water and mixing mechanically or by hand. Since hand mixing generates little shear force, we recommend allowing the fresh mortar to slake for 5 minutes and then stirring it again. This is usually unnecessary where mechanical mixers are employed.


If the product is used in applications other than those mentioned, the choice, processing and use of it is the sole responsibility of the purchaser. All legal and other regulations must be complied with.

Slight color variations of the polymer granulate may occure without impairing the product's functionality.

During storage, protect the product from contact with moisture. Prolonged storage at temperatures above 30 °C, especially in combination with pressure, humidity or exposure to sunlight, may result in blocking. Carefully seal any open containers and store them under suitable conditions. We recommend storing the product in a warehouse that provides cool and dry conditions. Do not store the product for more than six months, starting from the date at which it was received, unless the Certificate of Analysis contains a different date, which would take precedence. If the product is stored longer than recommended, it may still be used but users are advised to verify the properties required for the intended use.
