5 Reasons Why Your Business Needs hydrophobic fumed silica？

Fumed silica is available in both hydrophilic and hydrophobic forms. However, its hydrophilic nature makes it unsuitable for certain applications. Untreated fumed silica has many silanol groups on its surface, which absorb moisture and create a strong hydrogen bond network when added to a system. This bond network results in high viscosity and affects the stability of thickening and thixotropic properties. Polar solvents can easily break this bond network, causing instability in the system.

To overcome these issues, engineers treat fumed silica to convert its surface from hydrophilic to hydrophobic. Treating agents react with the surface silanol groups and form a layer of organic molecules, resulting in hydrophobic fumed silica. Hydrophobic fumed silica is beneficial in different product systems due to its good dispersing properties and ability to react with the product system through its silanol groups.

The Importance of Hydrophobicity in Fumed Silica

Hydrophobicity is a desirable property in fumed silica due to its many advantages in different applications. When treated to be hydrophobic, Its excellent dispersing properties, improved rheological properties, and moisture resistance make it a valuable material in various industrial and commercial applications.

Hydrophobic fumed silica has excellent dispersing properties, which enable it to form stable suspensions in water-based systems. It repels water, which reduces the tendency of the silica particles to clump together, resulting in a more uniform dispersion. This makes hydrophobic fumed silica useful in applications where uniformity of the suspension is important, such as in coatings and inks.

Hydrophobic fumed silica has improved rheological properties compared to hydrophilic fumed silica. The water-repellent nature of hydrophobic fumed silica makes it useful as a thickening and gelling agent in water-based systems, resulting in stable and consistent viscosity. This makes hydrophobic fumed silica ideal for use in adhesives, sealants, and other applications where controlled viscosity is critical.

Hydrophobic fumed silica has improved moisture resistance compared to hydrophilic fumed silica. The water-repellent nature of hydrophobic fumed silica makes it ideal for use in applications where moisture resistance is essential, such as in electronic coatings and sealants.
