Aerosil R 972 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 is highly porous. This substance exhibits excellent thixotropic properties, meaning it can thicken or gel when subjected to shear stress, making it useful as a thickening agent in various applications. Aerosil R 972 is commonly utilized in the formulation of paints, coatings, adhesives, and sealants, where it enhances viscosity and stability. Additionally, its hydrophobic nature improves the water repellency of formulations, making it suitable for use in outdoor applications. The material is also known for its ability to improve the flow properties of powders and reduce settling in suspensions. Safety data sheets indicate that while it is generally considered safe for handling, appropriate precautions should be taken to avoid inhalation of dust. Overall, Aerosil R 972 is valued for its versatility and performance in enhancing the physical properties of various products.
