VINNAPAS® EP 177 is an aqueous 60 % dispersion based on a copolymer of vinyl acetate and ethylene. It is produced without the use of plasticizers.


VINNAPAS® EP 177 films are noted for their:

  • Very good heat resistance
  • Good resistance to saponification
  • Excellent adhesion to a variety of substrates together with high cohesion
  • Aging resistance & light stability

Special applications

Thanks to the properties listed above, VINNAPAS® EP 177 can be used in the following applications:

  • Lamination of both plasticized and non plasticized PVC, polyamide, polyurethane foam, polystyrene foam and polyester to paper or to textile fabrics
  • Adhesion promoter for PVC coatings
  • Flocking adhesive for foam moldings
  • Binder for textile pigment printing formulations 



Polymer Dispersions

VINNAPAS® EP 177 is miscible in all proportions with most VINNAPAS® dispersions and many other aqueous polymer dispersions. However, storage tests should always be undertaken to check if dispersions are compatible.

To obtain a harder handle VINNAPAS ® DP 55 should be added to VINNAPAS® EP 177.


Fillers and Pigments

VINNAPAS® EP 177 is compatible with all the usual mineral fillers (chalk, gypsum, dolomite, aluminum hydroxide etc.). The latter product is especially suitable for the production of low smoke emission flame proofing compounds used in textile coatings. Depending on the requirements, further flame retardent agents such as derivatives of phosphorus may be added to the compound. Customer trials must always be carried out.

Fillers can be added dry but the addition of dispersants helps to disperse effectively them and increases the storage stability of the compund.



Suitable defoamers encompass silicone- or organic based products. Their efficacy and compatibility in the formulation chosen should always be checked.



Suitable thickeners include polyvinyl alcohol, fumed silica, cellulose or starch derivatives, polyacrylic acid derivatives and bentonite. Their efficacy and compatibility in the formulation chosen should always be checked.

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.

When the dispersion is stored in tanks, proper storage conditions must be maintained. VINNAPAS® EP 177 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® EP 177, 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

VINNAPAS® EP 177 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.
