HDK® N20ST

Synthetic, hydrophilic, amorphous silica, produced via flame hydrolysis. Standard product for industrial applications.



Properties

White colloidal powder of high purity.

HDK® N20ST 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® N20ST shows a lower thickening activity compared to HDK® N20.

HDK® N20ST is not suitable for pharmaceuticals, food and feed.

A good dispersion of HDK® N20ST is a must to assure optimum performance.

More detailed information about the application and processing of HDK® N20ST is available in our HDK-brochures and on the WACKER web site.

Packaging

HDK® N20ST is offered in following packaging:

  • pallet with paper bags: 10 kg bags
  • Big bags: 150 kg (big bags on pallets)

Storage

The 'Best use before end' date of each batch is shown on the shipping label and the certificate of analysis. HDK® N20ST 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.
