SIPERNAT® 320 DS is a very finely ground silica with good thickening and excellent flow improving properties, which benefits to many different applications, including:
- All types of fine powders (flow improvement)
- Defoamers / antifoams (rapid foam destruction after in- situ hydrophobization)
- Adhesives (auxiliary ingredient)
- Printing / offset inks (prevents misting and set-off, also used as an extender)
- RTV-2C/LSR silicone rubber-applications (viscosity adjustment)

Storage & Handling
- Storage Conditions
Our silica products are 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 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 pick up 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. Product 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.
