Aerosil R972 (Hydrophobic Fumed Silica) is a premium surface-treated synthetic amorphous silicon dioxide specifically engineered to deliver advanced rheology control, anti-settling performance, and moisture resistance in solvent-based and non-polar formulations. Produced through a flame hydrolysis process and subsequently treated with Dimethyldichlorosilane (DDS), Aerosil R972 features a hydrophobic surface that provides excellent compatibility with organic systems while maintaining outstanding thickening and thixotropic properties.

The unique particle structure of Aerosil R972 forms a three-dimensional network within liquid formulations, improving viscosity control, preventing pigment and filler sedimentation, and enhancing sag resistance during application. Its hydrophobic nature makes it particularly effective in coatings, adhesives, sealants, silicone rubber compounds, printing inks, and specialty chemical formulations where water resistance and long-term storage stability are critical requirements.

In adhesive and sealant systems, Aerosil R972 improves consistency, reinforces mechanical properties, and provides excellent anti-sag characteristics. In coatings, it acts as an efficient anti-settling and pigment stabilization additive while supporting corrosion protection performance. The product also serves as an effective free-flow and anti-caking agent in powder formulations, ensuring improved handling, storage, and processing efficiency.

With a typical BET surface area of approximately 110 m²/g, high purity silica content, low moisture absorption, and excellent dispersibility in organic media, Aerosil R972 is widely recognized as a versatile hydrophobic fumed silica for demanding industrial applications. Its combination of rheology modification, moisture resistance, reinforcement, and free-flow enhancement makes it a preferred choice for coatings, adhesives, sealants, printing inks, silicone systems, and advanced polymer formulations.
