About Aerosil (fumed Silica)
Aerosil, chemically known as fumed silica, is produced by the flame hydrolysis of silicon tetrachloride. Its unique structure consists of extremely fine, spherical particles that form a three-dimensional network when dispersed in liquids, providing excellent thixotropic properties.
In the Indian market, it is widely utilized across sectors including paints and coatings, silicone rubber manufacturing, and personal care. It serves as a critical performance additive for manufacturers looking to improve product stability, prevent pigment settling, and enhance the consistency of high-performance adhesives and sealants.
When procuring Aerosil in India, buyers should verify the specific surface area (m²/g) and surface treatment (hydrophilic vs. hydrophobic) to ensure compatibility with their specific solvent or polymer system. It is recommended to source from reputable distributors who provide technical data sheets and ensure moisture-free storage conditions.

Frequently Asked Questions
What is the price of Aerosil (fumed Silica) in India?
Aerosil (fumed Silica) prices in India vary by grade, order quantity and delivery location, and move with market conditions. To get the current price for your requirement, submit an enquiry on Chemical Dekho and receive verified quotes from suppliers and manufacturers within 24 hours.
What is the difference between hydrophilic and hydrophobic Aerosil?
Hydrophilic grades are water-dispersible and used for thickening polar systems, while hydrophobic grades are surface-treated to be water-repellent, ideal for non-polar systems.
Is Aerosil safe for cosmetic use?
Yes, high-purity grades are commonly used in cosmetics as an anti-caking agent and texture enhancer, provided they meet relevant purity standards.
How does Aerosil affect paint viscosity?
It acts as a thixotropic agent, meaning it increases viscosity at rest to prevent pigment settling and decreases viscosity under shear to allow for smooth application.
Does Aerosil expire?
It does not have a strict chemical expiration, but it is highly hygroscopic and should be used within 2 years to ensure optimal performance.
Can I use Aerosil in food applications?
Only food-grade fumed silica is permitted for food applications; standard industrial grades should not be used for food or pharma products.
