Packaging
HDK® N20 is offered in following packaging:
- pallet with paper bags: 10 kg bags
- Big bags: 150 kg (big bags on pallets)
- Silotruck: depending on size of truck, approx. 3.5 to 5 tons
Storage
The 'Best use before end' date of each batch is shown on the shipping label and the certificate of analysis.
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.
