Storage:
Our silica products are inert and chemically extremely stable. However, due to their high specific surface area, they can adsorb moisture and volatile organic compounds from the surrounding atmosphere. Products have to be stored in their original packaging (e.g. fully shrink-wrapped) or in sealed containers in a dry place away (or apart) from volatile organic substances. Even if a product is stored in these conditions, it can still pick up ambient moisture after a long time, which can cause it to exceed the stated ex works moisture content. For this reason, our recommended use-by date is 12 months after date of manufacture. Product more than 12 months old should be tested for moisture content before use in order to make certain that it is still suitable for the intended application.
