Fumed silica is used as thixotropic reinforcing agents, adjustments of viscosity and mechanical properties.
Silica filled RTV silicone glue can be pigmented to any desired color, and this is often required because the cured silicone cannot be painted. Typical pigments are titanium dioxide, carbon black, and a wide variety of metal oxides, chromates, sulfates, etc.
SiSiB provides both hydrophobic and hydrophilic type fumed silica.
