Hexamethyldisilazane (HMDS) is a chemical compound that is commonly used as a surface treatment for fumed silica to make it hydrophobic. The hydrophobic treatment involving HMDS enhances the dispersibility and compatibility of fumed silica in hydrophobic systems. The HMDS molecules attach to the surface of the silica particles, creating a water-repellent coating. This modification improves the performance of fumed silica in various applications.
Hydrophobic fumed silica, treated with HMDS, is widely used in industries such as paints and coatings, adhesives and sealants, cosmetics, plastics, rubber, and composites. It is added to formulations to improve properties like rheology, thixotropic behavior, stability, moisture resistance, and flow control.

PDMS (Polydimethylsiloxane) hydrophobic fumed silica refers to fumed silica particles that have been surface-treated with PDMS to make them hydrophobic. When PDMS is applied to the surface of fumed silica particles, it forms a hydrophobic coating. This modification enhances the dispersibility and compatibility of fumed silica in hydrophobic systems. The PDMS molecules attach to the silica surface, creating a water-repellent layer.
