VINNAPAS® EAF 7868

VINNAPAS® EAF 7868 is a very low Tg, aqueous polymer dispersion based on the monomers vinyl acetate and ethylene and acrylic esters. It is produced without the use of plasticizers. VINNAPAS® EAF 7868 shows excellent filler compatibility.



特性

  • High filler acceptance
  • Good adhesion to a variety of substrates (e.g. concrete, metal, wood, plastics)
  • Derived from low-volatile C1/C2 value streams
  • Can be formulated without the use of plasticizers
  • Allows for the formulation of low-odor, paintable sealants
  • Produced without APEO surfactants

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® EAF 7868 is especially suited as raw material for caulks and sealants applications. If needed, VINNAPAS® EAF 7868 based formulations can be modified with plasticizers. In order to ensure proper efficiency, we recommend the use of rather hydrophilic plasticizers like diisobutylphtalate (DIBP) or benzoate esters. VINNAPAS® EAF 7868 can be formulated also in combination with other polymer dispersions. If blended with alkaline dispersions, we recommend adjusting the pH of VINNAPAS® EAF 7868 prior to blending.

储存

When the dispersion is stored in tanks, proper storage conditions must be maintained. The product 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. Any longer periods for the maximum storage period that may be described in the Certificate of Analysis which accompanies each shipment of the product, take preference over this suggestion in which case the time period stated in the Certificate of Analysis shall be solely authoritative. Iron or galvanized iron containers and equipment are not recommended. Corrosion could result in discoloration of the dispersion or blends made from it in further processing. We therefore recommend the use of containers and equipment made of ceramic, rubberized or enameled materials, appropriately finished stainless steel, or plastic (rigid PVC, polyethylene or polyester resin). As polymer dispersions may tend to superficial film formation, skins or lumps may be formed during storage or transportation. A filtration process is thus 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.
