VINNAPAS® 240 HD

VINNAPAS® 240 HD is a multi-purpose construction dispersion for liquid and paste, cement-free binder technology, specifically suited for primers, ready-to-use tile adhesives and one-component dispersion-based water-proofing membranes. It is based on a flexible copolymer of styrene and acrylate and belongs to the product class VINNAPAS® HD which means that it provides a remarkable hydrophobic effect in addition to the excellent adhesion even under wet conditions. 



特性

  • VINNAPAS® 240 HD is a fine-particle 50% dispersion of a styrene/acrylic acid ester copolymer in water.
  • Films based on VINNAPAS® 240 HD possess high water resistance and excellent adhesion even in wet conditions.
  • VINNAPAS® 240 HD is also produced without the use of film-forming agents.

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® 240 HD is highly compatible with standard pigments and fillers. When using the dispersion in the preparation of filled, pasty compounds, it is advisable to raise its pH to a value > 7.5 prior to the addition of fillers. Since VINNAPAS® 240 HD contains no free ammonia, ammonia-free compounds can be prepared by adding KOH or 1)AMP-95®. Because of the low minimum film forming and glass transition temperature an addition of organic solvents or plasticizers is not necessary.


VINNAPAS® 240 HD is ideal for use in pasty construction and tile adhesives whose high adhesive strength is not affected by water or dampness. VINNAPAS® 240 HD can be used to produce construction adhesives and primers conforming to strict eco-labeling requirements.


For typical application fields of VINNAPAS® 240 HD, refer to the following application table. Please discuss additional applications with your WACKER customer representative.

包装

Non-returnable PE drums of 150 kg capacity (standard dispatch quantity: only fully-loaded pallets à 750 kg), non-returnable containers of 1 t capacity and road tankers.

储存

When the dispersion is stored in tanks, proper storage conditions must be maintained. VINNAPAS® 240 HD 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 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 VINNAPAS® 240 HD is adequately preserved during transportation and storage if kept in the original, unopened containers. When stored in tanks, the dispersion should be modified with a preservative to prevent microbial contamination. Suitable measures should be taken to ensure that the tanks are properly clean. In storage tanks in which the product is not stirred, it is advisable to cover the surface of the dispersion with 1 - 2 cm of water, to which a preservative has been added. This will prevent skin formation and microbial contamination. In the case of storage in silos, it is important that the air drawn into the silo when the product is discharged is also kept free of germs. As a rule, all finished products manufactured from polymer dispersions also require preservation. The type and extent of preservation will depend on the raw materials used and the anticipated sources of contamination. The compatibility and effectiveness of the preservatives should be checked for a given formulation. Preservative manufacturers will be able to advise you on the type and amount of conservation agent to use.
