VINNAPAS® 537 ED

VINNAPAS®-modified waterproofing membranes reliably protect buildings from water, even under hydrostatic pressure and at low temperatures. With VINNAPAS® 537 ED, WACKER now offers a novel cement compatible, vinyl acetate-ethylene based allround dispersion that complements its portfolio of polymer dispersions for waterproofing membranes. Due to its polymer base and its co-stabilization with polyvinyl alcohol & surfactant, VINNAPAS® 537 ED is suitable for several applications such as 2-component cementitious water proofing systems, as bonding agent or for jobsite mortar modification. Additionally VINNAPAS® 537 ED offers outstanding dilution stability.



特性

  • VINNAPAS® 537 ED is an aqueous polymer dispersion based on vinyl acetate and ethylene with a solid content of 60 %
  • The dispersion is produced without the use of alkyl phenol ethoxylate (APEO) containing compounds, also formaldehyde donor free. 
  • VINNAPAS® 537 ED is particulary suited for modifying mineral mortars. It improves the adhesion to inorganic and organic substrates, as well as crack-bridging and flexural strength.

  

VINNAPAS® 537 ED offers several advantages in a wide range of building chemical and construction applications and exhibits a high compatibility towards cement. The dispersion is characterized by a high bond strength combined with increased flexural strength, high flexibility and good compatibility with inorganic fillers like CaCO3.

We recommend VINNAPAS® 537 ED for applications such as waterproofing membranes (WPM), bonding agents, tile adhesives, putties and joint compounds and cement admixtures. VINNAPAS® 537 ED offers the following advantages:

 

  • Improvement of adhesion and cohesion
  • Significant increase in flexibility
  • High resistance to hydrostatic water pressure
  • Significant increase of crack-bridging ability
  • Vapor permeability
  • Excellent compatibility with cement
  • No odor

储存

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. Any longer periods for the maximum storage period that may be described in the Certificate of Analysis which accompanies each shipment of the product, take preference over this suggestion in which case the time period stated in the Certificate of Analysis shall be solely authoritative. 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. If the product is stored for a longer period, stirring is recomended before use.
