VINNAPAS® EN 421

VINNAPAS® EN 421 is an aqueous, self -crosslinking copolymer dispersion of vinyl acetate and ethylene, produced without the use of Alkyl Phenol Ethoxylate (APEO) based materials. It is particularly suited for the formulation of heat-curing or self-curing adhesives.



特性

VINNAPAS® EN 421 has the softness and flexibility typical of a vinyl acetate-ethylene copolymer adhesive base. The self-crosslinking nature of the dispersion provides excellent wet strength and good solvent resistance. VINNAPAS® EN 421 resists discoloration on aging and leaves no residual odor in the finished product.

储存

When VINNAPAS® EN 421 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® EN 421 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® EN 421 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® EN 421 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.
