VINNAPAS® EP 907

VINNAPAS® EP 907 is a vinyl acetate/ethylene based dispersion engineered for nonwoven applications requiring break down and re-dispersion in water. Substrates bound with VINNAPAS® EP 907 exhibit good dry tensile strength but essentially disintegrate when exposed to water.



特性

VINNAPAS® EP 907 may be used as a binder in nonwoven applications where stiff hand and dry tensile properties are required. When placed in water and agitated, substrates bound with VINNAPAS® EP 907 break down and disperse into smaller fragment of individual fibers. The dispersion is stabilized with an APEO free surfactant system and has a low formaldehyde level of less than 50 ppm.

免责声明

所提供之所有信息均基于我们当前所掌握的知识。尽管如此,我们不对其作任何担保、也不承担任何责任,并且保留在任何时候进行技术变更的权利。购买方应在预测试中对所提供之信息以及产品在既定应用中的适应性进行检查。任何时候都必须以合同条款与条件为准。此外,本免责申明还适用于与第三方权利有关之事宜,尤其是在德国境外。

VINNAPAS® EP 907 can be diluted with water prior to substrate application. Other additives can then be added under good agitation although Boron containing products may cause the product to gel. Surfactants can also be added to VINNAPAS® EP 907 to improve penetration of the binder into the substrate and improve absorbency of the finished product. Effective surfactant levels are 0.5 to 1.0% on dispersion solids.

VINNAPAS® EP 907 can be applied by a number of different application methods including saturation, spraying, foaming and print bonding. VINNAPAS® EP 907 performs well on various fiber types including cellulose, rayon, glass, and polyester based substrates. This dispersion is especially suited for use in dry wipe absorbent products. Due to the dispersion’s nonionic particle charge, VINNAPAS® EP 907 exhibits good compatibility with most cationic and anionic additives.

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.

储存

When VINNAPAS® EP 907 is stored in tanks, proper storage conditions must be maintained. If stored in the original, unopened containers at cool (below 30 °C), but frost-free temperatures VINNAPAS® EP 907 has a shelf life of 9 months from the date of manufacture. 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

VINNAPAS® EP 907 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. To maintain proper storage conditions appropriate measures should also be taken to ensure cleanliness of the tanks and pipes. In a storage tank in which VINNAPAS® EP 907 is not stirred, it is advisable to contact your biocide representative/supplier. Proper procedures must be set up in order to prevent microbial attack between necessary periodic tank cleaning and sanitization. These procedures will vary, since loading and unloading practices in each storage situation will differ slightly. 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.
