- Application Details
- VINNAPAS® 547 ED (ULS) 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 combined with increased flexural strength and good compatibility with inorganic fillers like CaCO3.
- VINNAPAS® 547 ED (ULS) 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.
Processing
VINNAPAS® 547 ED (ULS) exhibits a minimum film forming temperature of 0°C. Thus in practice, there is no need to add any further film-forming / coalescing agents to the formulation.
- Applications
- Cementitious Tile Adhesives
- External Thermal Insulation Composite Systems (ETICS/EIFS)
- Primer
- Tile Adhesives and Tile Grouts
- Waterproofing Membranes

Storage & Handling
- Shelf Life
- 9 Months
- Storage Information
- When the dispersion is stored in tanks, proper storage conditions must be maintained. The product has a shelf life of 9 months starting from the date of manufacture if stored in the original, unopened containers at temperatures between 5 and 30°C.
- 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 resin) is recommended.
- As polymer dispersions may tend to superficial film formation, skins or lumps may form during storage or transportation. Filtration is therefore recommended prior to utilization of the product.
Preservation for Transport, Storage and further Processing
- The product 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 the 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.
