Storage & Handling

Storage Conditions

ACEMATT® OK 500 is inert and extremely stable chemically. 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 ACEMATT® OK 500 in sealed containers in a dry, cool place, and removed from volatile organic substances. Even if ACEMATT® OK 500 is stored under these conditions, after a longer period it can still pick up ambient moisture over time, which could lead to its exceeding the specified moisture content. For this reason, our recommended use-bydate is 24 months after date of manufacture. ACEMATT® OK 500 more than 24 month sold should be tested for moisture content before use in order to make certain that it is still suitable for the intended application.
