Fumed Silica 200/380 (Hydrophilic, Amorphous)

Fumed Silica/Synthetic Amorphous Silica (Hydrophilic)

Fumed Silica, also known as pyrogenic silica, Aerosil®, or Cab-O-Sil®, is an ultra-fine white powder widely used as a thickener, anti-caking agent, and rheology modifier. Just a small amount can improve viscosity, prevent settling, and enhance flow control in resins, paints, adhesives, oils, and many other systems.

This versatile additive is available in Hydrophilic (untreated) 200/380 grade, making it suitable for both water-based and solvent/oil-based applications.

⚠️ Safety Note: Avoid inhaling dust. Use in a well-ventilated area or with a mask. Keep away from children.
     Storage: Store in a sealed container, dry and away from moisture.

Benefits & Advantages:

• Thickens liquids without changing color or finish
• Prevents sagging and dripping on vertical surfaces
• Improves extrusion and work-ability in pastes and coatings
• Stabilizes formulations by preventing pigment and filler settling
• Enhances texture, spreading, and application control
• Acts as an anti-caking agent in powders

Features:

• Grade: 200/380
• Extremely fine, lightweight, white fluffy powder
• High surface area for effective thickening at low concentrations
• Insoluble in water, stable across a wide range of systems
• Compatible with epoxy, resins, adhesives, coatings, and industrial formulations

Applications:

• Hydrophilic Fumed Silica (Water-attracting)
• Water-based paints, coatings, and inks
• Solvent-based paints and systems
