HDK® V16D

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


Properties

White colloidal powder of high purity.

HDK® V16D is applied as a thickening and thixotropic agent in silicone sealants.

HDK® V16D is not suitable for pharmaceuticals, food and feed.

A good dispersion of HDK® V16D is a must to assure optimum performance.
More detailed information about the application and processing of HDK® V16D is available in our HDK-brochures and on the WACKER web site

Packaging

HDK® V16D is offered in following packaging:

  • pallet with paper bags: 15 kg bags
  • Big bags: 180 kg (big bags on pallets)
  • Silotruck: depending on size of truck, approx. 5 tons

Storage

The 'Best use before end' date of each batch is shown on the shipping label and the certificate of analysis.HDK® V16D 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.
