Hydrophilic fumed silica with free silanol groups on the surface. Builds thixotropy through hydrogen bonding and reinforces silicone and organic matrices. Specific surface area 300 m2/g.

Hydrophilic fumed silica with free silanol groups on the surface. Builds thixotropy through hydrogen bonding and reinforces silicone and organic matrices. Specific surface area 380 m2/g.

Hydrophobic fumed silica, surface treated with hexamethyldisilazane. The treated surface resists moisture pick-up, keeps viscosity stable on storage, and disperses more easily in non-polar and reactive systems than untreated grades. Specific surface area 280 m2/g.
