Application Details

Properties

  • VINNAPAS® EP 701K (NJG) is a chemically stable at both high and low pH. It is compatible with an assortment of resins, solvents plasticizer and other modifiers as well as the other VINNAPAS ® EP dispersions.


Application

  • The low Tg and excellent adhesion to plastic substrates make VINNAPAS® EP 701K (NJG) especially useful in bonding PVC film to particle board, where the low water content reduces swelling of the wood due to protected by polyvinyl alcohol.
  • The excellent adhesion to difficult -to-bond surfaces shown by the dispersion is very useful in laminating films such as polyester, poly (ethylene terephthalate), poly (vinylidene chloride) and polystyrene to coated or uncoated papers.
  • It shows good adhesion to metalized films and tempered aluminum foil. The rapid setting speed of VINNAPAS® EP 701K (NJG) makes it very useful in high-speed packaging applications. The high-solids content is also important in bookbinding.
  • The clear film and excellent adhesion of the dispersion are important in film overlay laminating. Typical application fields of VINNAPAS® EP 701K (NJG) are as follows:
    • Packaging (window cartons and carton forming)
    • Envelop and Bookbinding
    • Textiles and Upholstery
    • PVC lamination and OPP wet lamination
    • Packaging for difficult-to-bond substrates.
    • Blending at vinyl acetate latex to reduce Tg without plasticizer migration
    • Can be used for non-solvent application
    • Paper coating

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.
