Fumed silica is with large specific surface area and strong adsorption ability. When in liquid, it can adsorb water molecules, then expand and fissure into super fine particles, these particles forms stable suspending agent , so fumed silica is easy to float. This property makes fume silica perfect additive for pesticide chemicals, like wettable pesticide powder, pesticide granules, carrier for water dispersible granules and dispersing agent. And ,fumed silica is with excellent chemical stability, it can keep consistent potency of pesticide even in rain or burning sunlight.
