CAB-O-SIL® TS-720 Fumed Silica

CAB-O-SIL® TS-720 by Cabot is a medium surface area fumed silica. It has been surface treated with polydimethylsiloxane (PDMS). This surface treatment results in hydrophobic silica with a very different performance than untreated silica. It is characterized by high purity, aggregated structure, submicron particle size, low bulk density and hydrophilic surface chemistry. CAB-O-SIL® TS-720 provides thickening efficiency, sag resistance or high film build, shear-thinning rheological behavior and stable rheological performance over time.
