Fumed silica is widely used as a thickening and reinforcing agent in various industries. In coatings and paints, it improves viscosity, prevents sagging, and enhances durability. It acts as a flow control agent in adhesives and sealants, ensuring smooth application and strong bonding. In the pharmaceutical sector, it is utilized as a stabilizer in tablets and powders to prevent caking and improve flowability. Fumed silica is also added to silicone rubber to enhance its mechanical properties, such as tensile strength and tear resistance. Additionally, it serves as a desiccant to control moisture in packaging and industrial processes. Its high surface area and light-diffusing properties make it valuable in cosmetics for improving texture and appearance.
