VINNAPAS® eco EN 1024

$VINNAPAS<sup>®</sup> eco EN 1024

VINNAPAS® eco EN 1024  is a self-crosslinking, aqueous polymer dispersion based on the monomers vinyl acetate and ethylene. VINNAPAS® eco EN 1024 is produced without the use of plasticizer.

 

VINNAPAS® eco EN 1024 is a fossil resources saving product. Whenever this product is bought, up to 100% of the fossil-based raw materials required for manufacturing this product can be replaced by sustainably certified renewable feedstock. The replacement is based on the REDcert² mass balance approach, audited by TÜV Nord. The exact amount of fossil raw material replaced depends on the selected product version and is specified in the REDcert² certificate, which can be found on the product page on the WACKER website.



Properties

VINNAPAS® eco EN 1024 is particularly suitable as a binder for soft and hydrophilic nonwovens. The dispersion provides good wet strength while the formaldehyde level on the nonwovens remains low. VINNAPAS® eco EN 1024 is particularly suitable for foam application.

General

VINNAPAS® eco EN 1024 is particularly suitable for foam application. However, it may also be applied via other methods (e.g. size press, impregnation or spraying).

Polymer Dispersions

VINNAPAS® eco EN 1024 can be mixed with most of the VINNAPAS® and VINNOL® dispersions and with many other anionic and/ or non-ionic aqueous polymer dispersions. However, the compatibility of the mixture should be tested by undertaking a storage test. Temperatures above 150 °C are necessary to achieve proper crosslinking.

Defoaming Agents

Suitable defoaming agents include 1)SILFOAM® SE1662, 2) FOAMASTER® WO 2310, 3)AGITAN® 352 or 4)Surfynol® DF58.

The compatibility and efficiency should be tested in any case.

Storage

When the dispersion is stored in tanks, proper storage conditions must be maintained. VINNAPAS® EN 1024 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. 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 then 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® eco EN 1024 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.
