Aerosil R 805 is a fumed silica, specifically a hydrophobic silica, characterized by its high surface area and low bulk density. It is produced through the flame hydrolysis of silicon tetrachloride, resulting in a fine, white powder that exhibits excellent thixotropic properties. This means it can increase the viscosity of liquids while maintaining a low viscosity under shear stress, making it useful as a thickening agent. Aerosil R 805 is often utilized in various applications, including coatings, adhesives, sealants, and plastics, where it enhances flow properties and improves the stability of formulations. Its hydrophobic nature allows it to repel water, making it suitable for use in moisture-sensitive applications. Additionally, it provides reinforcement and improves the mechanical strength of composite materials. Safety data sheets indicate that while it is generally considered safe to handle, inhalation of dust should be avoided, and appropriate personal protective equipment should be used during handling. Overall, Aerosil R 805 is valued for its versatility and effectiveness in enhancing the performance of various products across multiple industries.
