CAB-O-SIL® TS-530

CAB-O-SIL® TS-530 by Cabot is fumed silica surface treated with hexamethyldisilazane (HMDZ). This treatment replaces hydroxyls on the surface of the silica, resulting in increased hydrophobicity. Exhibits high purity, aggregated structure, submicron particle size, low bulk density and hydrophilic surface chemistry. Enables low viscosity build with good sag resistance without excessive unwanted increase in viscosity and anti-settling of pigments and fillers. CAB-O-SIL® TS-530 imparts dispersion improvement, flow and leveling, promoting a smooth surface for the end-product.
