VINNAPAS® 4115 N (GER)

VINNAPAS® 4115 N (GER) is a dispersible polymer powder for dry mix mortars, specifically suited for cementitious tile adhesives, wall and joint fillers. It is based on a hardcopolymer of vinylacetate and ethylene and belongs to the product class VINNAPAS® N which means that it has a neutral effect on rheology. VINNAPAS® 4115 N (GER) provides good adhesion strength very efficiently in tile adhesive at low polymer dosages.


Properties

VINNAPAS® 4115 N (GER) is a copolymer powder of vinyl acetate and ethylene and is dispersible in water.Mortars modified with VINNAPAS® 4115 N (GER) exhibit improved adhesion, flexural strength, deformability, abrasion resistance and are easier to process. Leveling, thixotropy and water retention are essentially unaffected.The product is ideal for use in combination with other mortar additives intended to enhance specific properties.VINNAPAS® 4115 N (GER) contains a fine mineral filler as antiblocking agent. It is produced without addition of organic solvents, plasticizers or filmforming agents.VINNAPAS® 4115 N (GER) has no effect on rheological properties and is a general-purpose powder in the upper Tg range. It is eminently suitable for formulating compounds of high ultimate strength and low emissions. 

For typical application fields of VINNAPAS® 4115 N (GER), 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® 4115 N (GER) 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.

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.
