More detailed information about the application and processing of HDK® D05 is available in our HDK-brochures and on the WACKER web site.

HDK® D05 is used as a filler in many organic and inorganic systems, where a high loading is of interest with low impact on rheology. Examples are the use in coatings and resins. HDK® D05 is used as a highly pure SiO² source.

HDK® D05 is not suitable for pharmaceuticals, food and feed.


HDK® D05 is offered in following packaging:

  • pallet with paper bags: 10 kg bags



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

HDK® D05 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.
