VINNAPAS® 7055 E

VINNAPAS® 7055 E is a dispersible polymer powder for dry mix mortars, specifically suited for waterproofing membranes as well as repair mortars. It is based on a very flexible terpolymer of vinyl acetate, ethylene and vinyl ester. VINNAPAS® 7055 E belongs to the product class  VINNAPAS® E which means that it provides enhanced properties like high tensile adhesion strength particularly on all substrates and very good crack-bridging properties even at low temperatures. 


Properties

  • VINNAPAS® 7055 E is a terpolymer powder of vinyl acetate, vinyl ester and ethylene and is dispersible in water.
  • The high ethylene content makes the resin soft and elastic, even at low temperatures.
  • Compounds modified with VINNAPAS® 7055 E 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® 7055 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® 7055 E has no effect on rheology and is suitable for low emission mortars.
  • It features high flexibility and excellent adhesion even at low temperatures to typical construction substrates.

For typical application fields of VINNAPAS® 7055 E, refer to the "Application" section . 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® 7055 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.
