Fumed Silica

Description :

Overview of Fumed Silica

Fumed Silica, also known as Pyrogenic Silica, is a high-purity, ultrafine white powder produced by the vapor-phase hydrolysis of silicon tetrachloride. It has an extremely high surface area and unique thixotropic (thickening) properties, making it an essential additive in coatings, adhesives, sealants, cosmetics, pharmaceuticals, and industrial formulations.

Its ability to control viscosity, improve flow properties, and enhance mechanical strength makes Fumed Silica a preferred choice in performance-driven industries. It is available in hydrophilic and hydrophobic grades depending on the application.

Other related products available on our website include Silicon Dioxide, Precipitated Silica, Silica Gel, and Quartz Powder, frequently used in coatings, fillers, and industrial chemical processes.

Applications of Fumed Silica

Coatings & Paints

• Improves thickening, anti-sagging, and anti-settling properties

• Enhances surface smoothness and durability

• Used in automotive coatings and high-performance paints

Adhesives & Sealants

• Acts as a reinforcing filler

• Controls flow behavior and prevents dripping

• Enhances mechanical strength and adhesion

Pharmaceuticals

• Used as a glidant in tablet and capsule manufacturing

• Improves powder flow and prevents clumping

• High-purity grade suitable for food and pharma applications

Cosmetics & Personal Care

• Provides a silky texture in powders and creams

• Absorbs oil and enhances product stability

• Used in skincare, makeup, and hair products

Silicone & Elastomers

• Increases tensile strength and elasticity

• Improves transparency and mechanical performance

Resins & Composites

• Used to control viscosity in epoxy and polyester resins

• Enhances curing and final strength in composites

Safety & Handling Guidelines

• Avoid inhalation of fine dust; use a dust mask

• Wear gloves, goggles, and protective clothing

Frequently Asked Questions (FAQs)

1. What is Fumed Silica used for?

   It is used as a thickening, anti-settling, and reinforcing agent in coatings, adhesives, sealants, pharmaceuticals, and cosmetics.
   
   

2. Is Fumed Silica the same as regular Silicon Dioxide?

   No. Fumed Silica has a much higher surface area, finer particle size, and unique rheology-modifying properties.
   
   

3. Is Fumed Silica safe?

   Yes, when handled properly. Avoid inhalation of dust and follow recommended safety practices.
   
   

4. Is Fumed Silica soluble in water?

   No, it is insoluble in water and most solvents.
   
   

5. How should Fumed Silica be stored?

   Store in a dry, sealed container away from moisture to maintain stability.
