HYDROPHOBIC FUMED SILICA-1

Hydrophobic fumed silica powder has several unique properties and applications. Some of its key features include:
1. Water repellency: The hydrophobic treatment makes the silica powder highly resistant to water absorption. This 

property is particularly useful in applications where moisture resistance is required.
2. Increased dispersibility: Hydrophobic fumed silica powder has improved dispersibility in non-polar solvents and 

polymers. This allows for better dispersion and incorporation into various systems.
3. Thixotropic behavior: The addition of hydrophobic fumed silica powder can impart thixotropic behavior to systems, 

meaning that they become more viscous when at rest but flow easily when agitated. This property is advantageous in 

applications such as coatings, adhesives, and sealants.
4. Reinforcing agent: Hydrophobic fumed silica powder can act as a reinforcing agent in various materials, including 

rubber, plastics, and composites. It enhances mechanical properties such as tensile strength, tear resistance, and 

dimensional stability.
5. Anti-settling agent: Due to its high surface area and hydrophobic nature, hydrophobic fumed silica powder can 

prevent settling or sedimentation in suspensions or emulsions. It helps maintain the stability and homogeneity of 

these systems.
