VINNAPAS® eco EAF 68

$VINNAPAS<sup>®</sup> eco EAF 68

VINNAPAS® eco EAF 68 is a plasticizer-free, aqueous polymer dispersion produced from the monomers vinyl acetate, ethylene and acrylate.

VINNAPAS® eco EAF 68 is a fossil resources saving product. Whenever this product is bought, up to 100% of the fossil-based raw materials required for manufacturing this product can be replaced by sustainably certified renewable feedstock. The replacement is based on the REDcert² mass balance approach, audited by TÜV Nord. The exact amount of fossil raw material replaced depends on the selected product version and is specified in the REDcert² certificate, which can be found on the product page on the WACKER website.



Properties

Considering that VINNAPAS® eco EAF 68 is a pressure sensitive adhesive, it exhibits excellent cohesion even at elevated temperatures.

Notable features of ​​​​​​​VINNAPAS® eco EAF 68 are:

  • Good shear resistance at high temperatures
  • Good adhesion to various materials used for floor coverings including e.g. PVC, linoleum, elastic and textile flooring

VINNAPAS® eco EAF 68 is especially suitable as a raw material to manufacture floor covering adhesives, especially for carpets and PVC floor coverings. VINNAPAS® eco EAF 68 can also be used for the production of pressure sensitive adhesives e. g. self-adhesive tapes, films, labels, sound and heat insulation mats. VINNAPAS® eco EAF 68 may additionally be used as adhesion promoter in adhesive formulations.

Storage

When the dispersion is stored in tanks, proper storage conditions must be maintained. VINNAPAS® eco EAF 68 has a shelf life of 6 months starting from the date of receipt 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® eco EAF 68, 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 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® eco EAF 68 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.
