Storage


Due to high specific surface and fine particle size, it can absorb moisture and volatile organic compounds from the surrounding atmosphere. So we recommend storing the products in a dry, cool place and removed from volatile organic substances.

Product more than 24 months should be tested for moisture content before use in order to make certain that it is still suitable for the intended application.
