VINNAPAS® 5549 H

VINNAPAS® 5549 H is a very strong hydrophobic dispersible polymer powder for dry mix mortars, specifically suited for water proofing membranes, ETICS, renders and plasters. It is based on a very flexible copolymer of vinyl acetate and ethylene and belongs to the product class VINNAPAS® H which means that it provides a remarkable hydrophobic effect in addition to the basic properties adhesion and flexibility.


Properties

  • VINNAPAS® 5549 H is a copolymer powder based on vinyl acetate and ethylene and is dispersible in water.
  • Mortars modified with VINNAPAS® 5549 H will have strong and lasting water repellency and significantly lowered water absorption.
  • Blended with inorganic binders the powder will provide very good workability with VINNAPAS® 5549 H have improved adhesion, flexibility, deformability, abrasion resistance and also provides a strong hydrophobic effect.
  • Due to the high ethylene content, this copolymer is highly flexible.
  • VINNAPAS® 5549 H will not have any effect on water-vapor transmission at common dosages.
  • VINNAPAS® 5549 H contains a fine mineral filler as an antiblocking agent.
  • VINNAPAS® 5549 H is a dispersible polymer powder with a strong hydrophobic effect in the lower Tg range. It has no effect on rheology.
  • Mortars modified with VINNAPAS® 5549 H exhibit very good workability and attain high strength when cured.
  • Additionally VINNAPAS® 5549 H provides strong hydrophobicity within the hardened mortar. It is especially suitable for adhesive mortars and embedding mortars in ETICS.

For typical application fields of VINNAPAS® 5549 H, 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® 5549 H 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.
