Used as a thickening and reinforcing agent in silicone rubbers and resins, improving mechanical strength and thermal stability. Acts as a free-flow agent in powders and prevents caking in food and pharmaceuticals. Enhances viscosity control in coatings, inks, and adhesives without significantly increasing weight. Provides anti-settling properties in liquid systems and improves scratch resistance in clear coatings. Also utilized in composite materials to enhance strength and durability at low loadings.
