CAB-O-SIL® M-5

CAB-O-SIL® M-5 by Cabot is medium surface fumed silica. It is widely used to provide thickening, thixotrophic (shear thinning), and anti-settling behavior in liquid systems. It is most efficient in non-polar to medium polarity systems. Offers an excellent balance of thickening efficiency and dispersibility. Exhibits high purity, aggregated structure, submicron particle size, low bulk density and hydrophilic surface chemistry. When blended into sticky and poorly flowing powder systems, CAB-O-SIL® M-5 reduces the angle of repose and improves powder flow. It can be used as a rheology control additive in all resin systems, when hydrophobicity and shelf stability are of only moderate concern.
