CAB-O-SIL® HS-5

CAB-O-SIL® HS-5 by Cabot is a high surface area fumed silica. It can increase the viscosity of liquid coating by imparting thickening, thixotropy (shear-thinning), and anti-settling. Exhibits high purity, aggregated structure, submicron particle size, low bulk density and hydrophilic surface chemistry. It is suitable for use in low to medium polarity systems. High shear dispersion equipment is recommended to realize the full benefits of CAB-O-SIL® HS-5. When very well dispersed, CAB-O-SIL HS-5 fumed silica provides good transparency in clear coatings.
