Hydrophobic fumed silica is a surface-treated silicon dioxide powder with the unique property of water repellency, meaning it does not easily interact with water but disperses well in organic systems. This makes it an essential functional filler in coatings, adhesives, sealants, silicone rubber, and lubricants.

In the silicone rubber industry, hydrophobic fumed silica enhances mechanical strength, wear resistance, and tear resistance while maintaining excellent flexibility. Additionally, it reduces the viscosity of silicone rubber, improving processing flowability and making products easier to mold and handle. In the coatings and ink industry, hydrophobic fumed silica serves as a thickening agent, providing superior thixotropy, ensuring uniform application, enhancing water resistance, and extending the durability of coatings.

Due to its excellent dispersibility and chemical stability, hydrophobic fumed silica is also used in cosmetics, pharmaceuticals, and food industries. It functions as an anti-caking agent and flowability enhancer in powdered cosmetics, oral formulations, and food additives. With increasing demand for high-performance materials, hydrophobic fumed silica is finding broader applications in advanced industries and fine chemical products.
