Application Details
  • HDK® T30 is applied as a thickening and thixotropic agent in many organic systems, e.g. in unsaturated polyesters, coatings, printing inks, adhesives and others.
  • HDK® T30 is used as a reinforcing filler in elastomers, mainly siliconeelastomers.
  • HDK® T30 is not suitable for pharmaceuticals, food and feed. A good dispersion of HDK® T30 is a must to assure optimum performance.

Packaging Information

HDK® T30 is offered in following packaging:

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

Storage & Handling

Storage Information

HDK® T30 should be stored in the original packaging in dry storage areas. 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.
