Used as a thickening and anti-settling agent in coatings and paints to improve viscosity and prevent pigment settling. Enhances mechanical strength and thermal insulation in rubber and polymer composites. Acts as a free-flow agent in powders and agricultural chemicals. Improves scratch resistance in adhesives and sealants. Widely applied in cosmetics for its matting effect and ability to absorb oils. Also utilized in electronics for encapsulation materials due to its excellent dielectric properties and thermal stability.

In pharmaceuticals, it facilitates controlled drug release and prevents powder caking for improved storage. In cement and construction materials, it boosts structural strength and minimizes cracking from internal pressures.

Overall, nano fumed silica significantly enhances mechanical, chemical, and physical properties in diverse products.
