CAB-O-SIL EH-5 fumed silica is a very high surface fumed silica which can increase the viscosity of liquid systems and provide significant reinforcement of silicone and organic rubbers. All untreated fumed silicas are characterized by: - High purity
- Aggregated structure
- Submicron particle size
- Low bulk density
- Hydrophilic surface chemistry
Application Information: Rheology Control for Coatings, Adhesive and other Liquid Systems: CAB-O-SIL EH-5 fumed silica can be used to provide thickening, thixotropic (shearthinning), and anti-settling behavior in liquid systems. Very high shear dispersion equipment is required to realize the full benefits of this product. For clear coatings and other systems, very well dispersed CAB-O-SIL EH-5 fumed silica provides greater transparency than lower surface area fumed silicas. Untreated fumed silicas are most efficient in non-polar to medium polar systems for building viscosity and improving sag-resistance. For more polar systems, treated fumed silicas may be more efficient. Reinforcement of Silicone and Organic Rubber: CAB-O-SIL EH-5 fumed silica can be used for reinforcement of silicone rubber and can be used to reinforce organic rubbers. It imparts good increase in hardness, tensile and elongation. For clear silicone rubber applications, well-dispersed CABO-SIL EH-5 fumed silica provides excellent transparency.Information provided by Cabot Corporation |
