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。

HDK® N20D is applied as a thickening and thixotropic agent in many organic systems, e.g. in unsaturated polyesters, coatings, printing inks, adhesives, cosmetics and others.
HDK® N20D in comparison to non densified HDK® N20 provides an increased bulk density, a faster incorporation, but a slightly reduced thickening activity.

HDK® N20D is not suitable for pharmaceuticals, food and feed.


A good dispersion of HDK® N20D is a must to assure optimum performance.

More detailed information about the application and processing of HDK® N20D is available in our HDK-brochures and on the WACKER web site.
 

包装

HDK® N20D is offered in following packaging:

  • pallet with paper bags: 15 kg bags
  • Big bags: 220 kg (big bags on pallets) 
  • Silotruck: depending on size of truck, approx. 3.5 to 5 tons

储存

The 'Best use before end' date of each batch is shown on the shipping label and the certificate of analysis.

HDK® N20D should be stored in the original packaging in dry storage areas. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons. Due to the high surface area HDK® adsorbs volatiles and should be protected from humidity and volatiles. If single bags are taken away from an original pallet, the remaining bags of this pallet must again be protected against humidity and volatiles.
