Product Description:
Fumed silica is widely used as a thickening and reinforcing agent in various industries. In paints and coatings, it improves viscosity, prevents sagging, and enhances durability. It is a key component in adhesives and sealants, where it provides thixotropic properties, ensuring easy application and strong bonding. In the pharmaceutical industry, it acts as a flow agent in powders and tablets, improving manufacturing efficiency. Fumed silica is also utilized in silicone rubber to enhance mechanical strength and thermal stability. Additionally, it serves as a filler in composites, improving their structural integrity and performance. Its high surface area and porosity make it valuable in catalysts and as a desiccant in moisture-sensitive applications.
