Fine-Grained Hydrophobic Fumed Silica Matting Powder

Characteristics:

Hydrophobic Fumed Silica is created by treating the Fumed Silica particles with various hydrophobic materials, such as silanes 

or polymers. This treatment modifies the surface of the silica particles, making them repel water and other polar liquids. As a 

result, hydrophobic fumed silica is not easily wetted by water and tends to form aggregates or clumps when exposed to liquid.

Hydrophobic fumed silica is a type of silica that has been treated to repel water. Here are some of its main characteristics:
1. Water repellency: Hydrophobic fumed silica has a high degree of water repellency. This means that it does not readily absorb 

or interact with water molecules, making it useful in applications where contact with water needs to be minimized.
2. Surface modification: The hydrophobic treatment of fumed silica involves coating the surface of the silica particles with a 

hydrophobic material. This modification alters the surface chemistry of the silica, making it less prone to wetting by water.
3. Increased dispersibility: Hydrophobic fumed silica has improved dispersibility in nonpolar liquids and polymers compared to 

untreated fumed silica. This makes it easier to incorporate into various formulations and achieve homogeneous mixtures.
