CAB-O-SIL® fumed silica is a free-flowing powder product available as untreated and treated grades. CAB-O-SIL’s versatility is related to its high degree of purity, amorphous nature and 3-dimensional structure, which leads to its excellent performance.

Widely used as free flow & anti-caking agent in hygroscopic powder ingredients such as in food, pharma and many industrial technical powders. CAB-O-SIL® grades are used for rheology control, viscosity stability, antisettling and anti-sag application in many liquid & resin systems like inks, paints, coatings etc. Additionally, they find application as
reinforcement fillers that provide transparency in adhesives, sealants, elastomers and rubber applications.

The manufacturing facility is located at Mettur, Tamil Nadu.

Fumed Silica is primarily used to:

• Improve flow properties of powdered product
• Provide rheology control for liquids
• Control sag of liquids (thixotropy)
• Reduce caking of powders in storage
• Prevent waxy products from congealing
• Serve as a dry carrier for liquids and as emulsification agents
• Act as a grinding agent
• Allow encapsulation of flavouring oils
• Serve as a reinforcing filler in elastomers
