VINNAPAS® eco 7220 E
VINNAPAS® eco 7220 E is a multi-purpose dispersible polymer powder for dry mix mortars, specifically suited for tile adhesives and tile grouts. It is based on a flexible copolymer of vinylacetate, ethylene and methylmethacrylate and belongs to the product class VINNAPAS® E which means that it provides enhanced properties, like excellent adhesion after water immersion and flexibility.
The technical properties of VINNAPAS® eco 7220 E and VINNAPAS® 7220 E are identical.
VINNAPAS® eco 7220 E is a fossil resources saving product. Whenever this product is bought, up to 100% of the fossil-based raw materials required for manufacturing this product can be replaced by sustainably certified renewable feedstock. The replacement is based on the REDcert² mass balance approach, audited by TÜV Nord. The exact amount of fossil raw material replaced depends on the selected product version and is specified in the REDcert² certificate, which can be found on the product page on the WACKER website.
- VINNAPAS® eco 7220 E is a polymer powder and is dispersible in water.
- VINNAPAS® eco 7220 E is ideal for modifying cementitious mortars, e. g. tile adhesives.
- VINNAPAS® eco 7220 E contains a fine mineral filler as an antiblocking agent and is produced without the addition of organic solvents, plasticizers and film-forming agents.
- VINNAPAS® eco 7220 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 immersion in water and exposure to freeze/thaw cycles.
For typical application fields of VINNAPAS® eco 7220 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 7220 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.
