Storage & Handling

Storage Conditions
  • However, due to their high specific surface area, they can absorb moisture and volatile organic compounds from the surrounding atmosphere.
  • Therefore, we recommend storing the products in sealed containers in a dry, cool place, and removed from volatile organic substances.
  • Even if a product is stored under these conditions, after a longer period it can still pickup ambient moisture over time, which could lead to its exceeding the specified moisture content.
  • For this reason, our recommended use-by date is 24 months after date of manufacture.
  • Products more than 24 months old should be tested for moisture content before use in order to make certain that it is still suitable for the intended application.
