An excellent thixotropic agent which is used to control viscosity of mixed epoxy systems Can be used alone for a very smooth, non-sagging, high strength mixture or combined with fillers or fibers to make them non-sagging can also be used as fly floatant Also referred to as colloidal or fumed silica CAB-O-SIL M-5 fumed silica is a medium surface fumed silica which enables a significant increase in viscosity in liquid polyester or epoxy systems, free flow of high purity powders and reinforcement of silicone and organic rubbers. Aggregated structure Sub-micron particle size Low bulk density Hydrophilic surface

• Imparts good increase in hardness, tensile and elongation. Imparts significant increase in viscosity in liquid systems
• Also referred to as colloidal or fumed silica
