VINNAPAS® 4021 T

VINNAPAS® 4021 T is a copolymer powder of vinyl acetate and ethylene and is dispersible in water.


Properties

  • Compounds modified with VINNAPAS® 4021 T exhibit improved adhesion, flexural strength, deformability and abrasion resistance and are easier to process.

  • Combinations with cement and gypsum can provide mortars which exhibit non-sag properties.

  • VINNAPAS® 4021 T contains a fine mineral filler as an antiblocking agent. It is produced without the use of organic solvents, plasticizers and film-forming agents.

  • VINNAPAS® 4021 T is a non-slump dispersible polymer powder in the medium Tg range. It is suitable for formulating compounds that must exhibit good non-slump properties.


For the production of ready-mixed dry mortars, such as adhesives and patching compounds, blend VINNAPAS® 4021 T 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.

For typical application fields of VINNAPAS® 4021 T, refer to the "Application" section.  Please discuss additional applications with your WACKER customer representative.

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.
