CAB-O-SIL® is synthetic, colloidal, anhydrous silicon dioxide. It is a unique material because it has an extremely small particle size and unusual particle characteristics. It is amorphous, white in colour and free flowing.

Because of its inert nature, Fumed Silica finds diverse applications in pharmaceuticals, food as well as cosmetics. It is a versatile thickening agent, used to thicken paint, inks in the screen printing industry, epoxy, polyester and urethane. When mixed into liquid resins, CAB-O-SIL® functions as a resin thickener or flow control agent and sometimes as an anti-settling, anti-caking agent. It is used as a glidant in pharmaceutical applications.

CAB-O-SIL® is capable of imparting significant properties in the following areas: Flow control including anti-caking, thickening and thixotropy, anti-settling during storage, a higher extrusion rate at lower pressure, anti-sag during curing, improved tear strength, elasticity, improved water resistance and gloss reduction. A carrier for catalysts and a suspension and emulsifying aid, CAB-O-SIL® can also aid anti-slip and anti-blocking properties.

Major applications include pharmaceutical, paint formulations, resin and rubber, cable gel and silicone.
