Common questions about Precipitated Silica in agro chemicals applications
Precipitated silica's highly porous structure and high surface area allow it to absorb moisture that would otherwise cause powder particles to stick together. By absorbing this moisture and creating a physical barrier between particles, it maintains free-flowing characteristics even in humid storage conditions.
Precipitated silica particles create a loose, porous structure in WP formulations that allows water to penetrate rapidly between active ingredient particles, improving wettability and dispersion speed when mixed with water, ensuring faster and more uniform spray preparation.
Agrochemical-grade precipitated silica typically has a BET surface area of 100–250 m²/g, with higher surface area grades offering better moisture absorption and anti-caking performance.
Precipitated silica is typically used at 1–5% by weight in WP and SP formulations. The exact dosage depends on the moisture sensitivity of the active ingredient, storage conditions, and required flowability characteristics.
No. Precipitated silica is chemically inert and does not react with or degrade agrochemical active ingredients. It has no biological activity of its own and does not affect the efficacy of the active ingredient in the formulation.
Yes. Precipitated silica is often used in combination with carriers like China Clay or calcium carbonate in WP formulations. The silica provides anti-caking and flowability, while the other carriers provide bulk, whiteness, and cost optimization.
