High Purity Nano Powder Hydrophobic Fumed Silica Powder

Feature
High purity nano powder Hydrophobic Fumed Silica powder is a type of Silica Powder that has been treated to be hydrophobic, 

meaning it repels water. Fumed Silica is a fine, white powder that is made by burning silicon tetrachloride in a flame of 

hydrogen and oxygen. The resulting particles are very small, with a high surface area, which gives fumed silica unique 

properties.

The hydrophobic treatment of fumed silica involves coating the surface of the particles with a hydrophobic substance, such 

as a silane or silicone oil. This coating prevents water from wetting the surface of the particles, making them water-repellent.

High purity nano powder hydrophobic Fumed Silica Powder is used in a variety of applications. It is commonly used as a 

Thickening Agent in paints, coatings, and adhesives, where it helps to improve the rheological properties and stability of the 

formulations. It can also be used as a reinforcing filler in rubber and plastic composites, where it improves mechanical 

properties such as strength and tear resistance. Additionally, hydrophobic fumed silica powder can be used as an anti-caking 

agent in powders and granules, as a flow aid in powders, and as a Matting Agent in coatings.

The high purity of this type of fumed silica powder ensures that it has a low level of impurities, making it suitable for use in 

sensitive applications where purity is important. The nano-sized particles of the powder provide a large surface area, which 

enhances its performance in various applications.
