VINNAPAS® 547 ED

VINNAPAS® 547 ED is a versatile polymer dispersion with high water resistance and excellent compatibility towards hydraulic binders, pigments and fillers.



Properties

  • VINNAPAS® 547 ED  is a dispersion based on vinyl acetate and ethylene.
  • VINNAPAS® 547 ED is produced without using formaldehyde donors and without adding plasticizers or organic solvents.

Disclaimer

All the information provided is in accordance with the present state of our knowledge. Nonetheless, we disclaim any warranty or liability whatsoever and reserve the right, at any time, to effect technical alterations. The information provided, as well as the product's fitness for an intended application, should be checked by the buyer in preliminary trials. Contractual terms and conditions always take precedence. This disclaimer of warranty and liability also applies particularly in foreign countries with respect to third parties' rights.

VINNAPAS® 547 ED  offers several advantages in a wide range of building chemical and construction applications. It exhibits a high compatibility towards cement and its influence on cement setting is marginal. The dispersion is characterized by high bonding strength and good compatibility with inorganic fillers like CaCO3. VINNAPAS® 547 ED  is compatible with other dispersions (such as styrene/acrylic and pure acrylic dispersions) and especially suitable for use in applications such as waterproofing membranes (WPM), tile adhesives, external thermal insulation composite systems (ETICS/EIFS), primer and bonding agents as well as cement admixtures.

For typical application fields of VINNAPAS® 547 ED  you can refer to the section "application". Please discuss additional applications with your WACKER customer representative

Processing 

VINNAPAS® 547 ED can be blended with most anionic and/or nonionic aqueous polymer dispersions. However, the compatibility of the mixture should be tested by means of storage tests.

VINNAPAS® 547 ED has a minimum film forming temperature of 0°C. Therefore, there is no need to add any film-forming or coalescing agents to the formulation.

VINNAPAS® 547 ED is compatible with common pigments and extenders and is easy to process.

If the product is used in applications other than those mentioned, the choice, processing and use of the product is the sole responsibility of the purchaser. All legal and other regulations must be complied with.

Storage

When the dispersion is stored in tanks, proper storage conditions must be maintained. VINNAPAS® 547 ED  has shelf life of 9 months if stored in the original, unopened containers at temperatures between 5 and 30 °C. Any longer periods for the maximum storage period that may be described in the Certificate of Analysis which accompanies each shipment of  VINNAPAS® 547 ED , take preference over this suggestion in which case the time period stated in the Certificate of Analysis shall be solely authoritative. Please refer to "Best use before date" on the packaging label. Storage beyond the date specified does not mean that the product can't be used anymore, but the user should perform a quality check on the properties necessary for the intended application. Iron or galvanized-iron equipment and containers are not recommended because the dispersion is slightly acidic. Corrosion may result in discoloration of the dispersion or its blends when further processed. Therefore the use of containers and equipment made of ceramics, rubberized or enameled materials, appropriately finished stainless steel, or plastic (e.g. rigid PVC, polyethylene or polyester resins) is recommended. As polymer dispersion may tend to superficial film formation, skins or lumps may form during storage or transportation. Filtration is therefore recommended to utilization prior of the product.

Preservation for Transport, Storage and further Processing

VINNAPAS® 547 ED  is adequately preserved during transportation and storage if kept in the original, unopened containers. However, if it is transferred to storage tanks, the dispersion should be protected against microbial attack by adding a suitable preservative package.

Measures should also be taken to ensure cleanliness of the tanks and pipes. In unstirred tanks, a layer of preservative-containing water should be sprayed onto the surface of the dispersion to prevent the formation of unwanted skin and possible attack by microorganisms. The thickness of this water layer should be < 5 mm for low viscosity dispersions and up to 10-20 mm for high viscosity products. Proper procedures - periodic tank cleaning and sanitization - must be set up in order to prevent microbial attack. Contact your biocide representative/supplier for further plant hygiene recommendations. Measures should be taken to ensure that only clean air enters the tank when the dispersion is removed.

Finished products manufactured from polymer dispersions usually also require preservation. The type and scope of preservation will depend on the raw materials used and anticipated sources of contamination. The compatibility with other components and the efficacy of the preservative should always be tested in the respective formulation. Preservative manufacturers will be able to advise you about the type and dosage of preservative required.
