VINNAPAS® EP 606K (NJG)

VINNAPAS® EP 606K (NJG)is a high-viscosity, low fomaldehyde and low free VAM residue vinyl acetate ethylene copolymer dispersion. VINNAPAS® EP 606K (NJG) exhibits good machinability and strong wet tack. It does provide better adhesion to films such as polyvinyl chloride. It also has very high plasticizer/solvent viscosity thickening responses. 



Properties

  • Good adhesion to various plastic surfaces
  • Permanently flexible adhesive joints
  • High cohesion

Properties

VINNAPAS® EP 606K (NJG) ic chemcally stable at both high and low pH. It is compatible with an assortment of resins, solvents, plasticizers and other modifiers as well the other VINNAPAS ® EP dispersions.

Application

VINNAPAS® EP 606K (NJG) offers several advantages in relatively slow-speed PVC laminating applications because of its higher starting viscosity.VINNAPAS® EP 606K (NJG) bonds such widely diversified substrates as paper, wood, cotton cloth, nylon cloth, hardboard, urethane foam and certain types of coated paperboard.

Typical applications fields of VINNAPAS® EP 606K (NJG) are follows:

  • Packaging (window cartons and carton forming)
  • Bookbinding
  • Textiles and Upholstery
  • PVC lamination and OPP lamination

The high plasticizer/solvent viscosity thickening response of VINNAPAS® EP 606K (NJG) is very useful to develop various high-performance waterborne adhesives with one VAE copolymer dispersion.

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.

Storage

When the dispersion is stored in tanks, proper storage conditions must be maintained. VINNAPAS® EP 606K (NJG) has shelf life of 9 months starting from the date of receipt if stored in the original, unopened containers at temperatures between 5 and 30 °C. Please refer to "Best use before date" on the packaging label. Storage beyond the date specified does not mean that the product can't be used anymore, but the user should perform a quality check on the propertiesnecessary for the intended application.

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® EP 606K (NJG) 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.
