Properties : VINNAPAS® EP 6411 is a suitable raw material for adhesives, preferably for bonding plastic films and paper. Notable features are high heat resistance, good adhesion to various plastic surfaces, permanently flexible adhesive joints, fast setting and good machine running characteristics.
Application
- General : VINNAPAS® EP 6411 can be used to produce adhesives which achieve bonds to remain permanently flexible and resistant to aging. Such adhesives are noted for their very good adhesion even to usually difficult to stick plastic or varnished surfaces. Because of the variety of surfaces encountered, pre-trials to check the adhesion to the surfaces to be bonded should always be undertaken. The base polymer of VINNAPAS® EP 6411 shows a high cohesive strength even at elevated temperatures and therefore VINNAPAS® EP 6411 can be used to produce adhesives with very good heat resistance. Suitable formulated adhesives based on VINNAPAS® EP 6411 show a rapid increase in bond strength even after only a short setting time. It should be emphasized that VINNAPAS® EP 6411 is almost low on odor.
- Special : VINNAPAS® EP 6411 can be used as a raw material for :
- PVC furniture foils adhesives which show particularly high bond strength at elevated temperatures. Because of the variation in the bonding properties of foils, pre-trials should be undertaken to check the adhesion, especially at low temperatures.
- Adhesives for laminating plastic films, especially plasticized PVC, to cardboard, paper, textiles and leather for book covers, office files, high quality packaging and cases.
- Adhesives for the production and sealing of varnished and coated cartons und packaging.
- As VINNAPAS® EP 6411 is produced without the use of plasticizers it offers particular advantages when the bonded parts get in contact with products which are sensitive to plasticizers. For example varnished and printed surfaces or where packaged goods are not allowed to contact plasticizer containing adhesive joints.

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.
