CAB-O-SIL fumed silica provides powder free-flow and anti-caking properties. When added to agrochemical powders, it acts as a spacer between powder particles to reduce attractive forces, it acts as a free-flow aid that helps minimize dust and prevent caking, thus improves the accuracy and precision of fertilizer applications and helps improve plant nutrition. Hydrophilic fumed silica also enables easy dispersion of powder-based fertilizer or crop production inputs in water, so that active ingredients are evenly applied on fields As the silica loading increases, the powder flowability improves, transforming fertilizer from sticky to free flowing powders.

Fumed silica delivers critical benefits when added to water and oil-based dispersions. Fumed silica promotes long-term suspension of active ingredients in water and oil-based formulations by inhibiting agglomeration and settling of active ingredients. Fumed silica allows a consistent concentration of active ingredients during application, acts as an emulsion stabilizer and suppresses phase separation in liquids, does not promote microbial growth and it forestalls clogging of nozzles.

Fumed Silica when incorporated into seed coatings, it suppresses pre-mature germination by controlling the rate of moisture penetration, resulting in higher germination rates and crop yield. It also inhibits seed from rotting when stored in warehouses with moisture or elevated humidity, resulting in less waste for agriculture retailers and commercial grower.

The addition of untreated (hydrophilic) fumed silica in a seed coating or granule can increase penetration of water through the coating or into a granule, whereas the addition of treated (hydrophobic) fumed silica in a seed coating can reduce or slow penetration of water through the coating to the seed.
