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.
特性
- 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.

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.
