- Application Details
- HDK® N20 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® N20 is used as a reinforcing filler in elastomers, mainly silicone-elastomers.
- HDK® N20 acts as a free flow additive in the production of technical powders.
- HDK® N20 is not suitable for pharmaceuticals, food and feed. A good dispersion of HDK® N20 is a must to assure optimum performance.

Safety & Health
- Safety Notes
HDK® N20 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.
