CAB-O-SIL® TS-720

CAB-O-SIL® TS-720 by Cabot is a medium surface area fumed silica surface treated with polydimethylsiloxane (PDMS). This surface treatment results in a hydrophobic silica with a very different performance than untreated silica. Acts as a rheology modifier imparting good thickening efficiency, sag resistance (or film build) and anti-settling. Exhibits high purity, aggregated structure, submicron particle size, low bulk density and hydrophilic surface chemistry. The hydrophobic surface of CAB-O-SIL® TS-720 introduces very little moisture into polyurethane coating systems, retarding premature cross-linking of moisture cured systems. Provides stable rheological performance over time.
