VINNAPAS® 7220 E

VINNAPAS® 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. VINNAPAS® 7220 E is part of our standard range, offering you the best-in-class solution for a wide variety of applications.


Properties

  • VINNAPAS® 7220 E is a polymer powder and is dispersible in water.
  • VINNAPAS® 7220 E is ideal for modifying cementitious mortars, e. g. tile adhesives.
  • VINNAPAS® 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® 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® 7220 E, refer to the section "application". Please discuss additional applications with your WACKER customer representative.

Processing

For the production of ready-mixed dry mortars, such as adhesives and patching compounds, blend VINNAPAS® 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.


 

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.

Storage

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.
