HDK® N20P is used as a thixotropic agent in the production of tooth pastes and sulfuric acid gel batteries.

HDK® N20P is not suitable for pharmaceuticals, food and feed.

A good dispersion of HDK® N20P is a must to assure optimum performance.

Packaging

HDK® N20P is offered in following packaging:

  • pallet with paper bags: 20 kg bags

Storage

The 'Best use before end' date of each batch is shown on the shipping label and the certificate of analysis. HDK® N20P 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.
