CAB-O-SIL® TS-610

CAB-O-SIL® TS-610 by Cabot is a low surface area fumed silica surface modified with dimethyldichlorosilane. The treatment replaces some of the hydroxyls on the surface of the silica, resulting in increased hydrophobicity. It controls rheology in non-polar to medium polarity inks and coatings. Exhibits high purity, aggregated structure, submicron particle size, low bulk density and hydrophilic surface chemistry. The hydrophobic surface of CAB-O-SIL® TS-610 has a lower capacity for moisture adsorbtion than untreated fumed silica of equal base silica surface area. Hence, it will introduce and adsorb less moisture when used as a free-flow additive in powder systems. It is an effective free-flow additive for powder systems that are moisture sensitive.
