Hydrophobic Silica
Hydrophobic silica is a type of silica material that has been chemically modified to repel or be resistant to water. This modification alters the surface properties of silica nanoparticles, making them less prone to interacting with water molecules. The modification process typically involves treating the surface of the silica nanoparticles with hydrophobic compounds, such as alkylsilanes or fluorosilanes. These compounds form a hydrophobic layer on the surface of the silica particles, effectively blocking interactions with water molecules. Hydrophobic silica finds numerous applications across various industries. For example, it is used as an additive in coatings, paints, and sealants to improve water repellency and durability. In the pharmaceutical and food industries, hydrophobic silica can be used as an anti-caking agent to prevent clumping in powdered products. Additionally, it is utilized in rubber and plastic composites to enhance their water resistance and mechanical properties.

Hydrophobic fumed silica is a premium surface-treated SiO2 powder widely used as a rheology modifier and thickening agent in coatings, sealants, adhesives, and rubber compounds. This chemically modified pyrogenic silica repels moisture and provides excellent anti-caking performance in powder systems, making it ideal for export-grade bulk applications. Sourced from leading global producers, it meets rigorous industrial specifications and is available in various hydrophobicity grades suitable for cosmetics, paints, and precision manufacturing. Pricing reflects the specialized surface treatment process and is quoted on a CIF/CFR basis for international trade.
