VINNAPAS® EP 760

VINNAPAS® EP 760 is a unique rapid-setting vinyl acetate-ethylene copolymer dispersion. It stands out as more than just a high-solids version of the VINNAPAS® EP series. This polymer exhibits exceptional adhesion to challenging substrates that are typically difficult to bond, such as polyester, polyethylene terephthalate, tempered aluminum foil, and polystyrene.

Application Details

Properties

  • VINNAPAS® EP 760 can be compounded in a manner similar to VINNAPAS® EP706 and accepts all the common plasticizers, solvents, tackifiers and fillers used with vinyl acetate ethylene dispersions.
  • The dispersion combines very highsolids content with a low viscosity - a combination that permits the addition of very high filler loadings, resulting in adhesive formulations with solid contents as high as 80 percent, or even greater.
  • VINNAPAS® EP 760 accepts extraordinary amounts of fillers, such as clay and calcium carbonate, without excessive thickening. It also does not thicken rapidly on the addition of plasticizers and solvents, which is a useful property where high solids at moderate viscosities are required.
  • VINNAPAS® EP 760 is very shear stable, which means that it can be applied on high-speed packaging machines using roll, extrusion or spray equipment.
  • The dispersion dries to a slightly tacky, clear, water-resistant film. It is compatible with other vinyl acetate-based polymers, including PVAc homopolymer, Acrylic lattices and VINNAPAS® copolymer dispersions.

Application

  • VINNAPAS® EP 760 high-solids content and excellent adhesion to plastic substrates make it especially useful in bonding PVC film to particle board, where the low water content reduces swelling of the wood.
  • The excellent adhesion to difficult-tobond 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 760 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 760 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

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.
