Products

AEROSIL® R 202 is a hydrophobic fumed silica grade, treated with a polydimethylsiloxane. This product can be used in defoamer formulations for sedimentation stabilization and due to its high hydrophobicity as defoaming component.

AEROSIL® 200 is a hydrophilic fumed silica with a specific surface area of 200 m²/g.

AEROSIL® R 972 is hydrophobic fumed silica grade treated with DDS (Dichlordimethylsilane). The moderate hydrophobicity of these AEROSIL® products is suited for defoaming properties in the presence of appropriate hydrophobic liquids. They are recomended for improving the sedimentation stability of defoamer dispersions as well.

SIPERNAT® 22 S is a finely milled, hydrophilic silica. It is primarily used as a free-flow agent in other applications. SIPERNAT® 22 S can also be used in-situ hydrophobized in defoamers. The use of an alkaline catalyst is recommended.

AEROSIL® R 974 is hydrophobic fumed silica grades treated with DDS (Dichlordimethylsilane). The moderate hydrophobicity of these AEROSIL® products is suited for defoaming properties in the presence of appropriate hydrophobic liquids. They are recommended for improving the sedimentation stability of defoamer dispersions as well.

AEROSIL® R 812 S is hydrophobic fumed silica grade treated with HMDS (Hexamethyldisilazane). It is even more hydrophobic than AEROSIL® R 812 and convenient for stabilizing a defoamer and well suitable as a component of foam control agents.

AEROSIL® 300 is a hydrophilic fumed silica with a specific surface area of 300 m²/g.

SIPERNAT® 22 LS is a very finely milled, hydrophilic silica. It is primarily used as a free-flow agent in other applications.

AEROSIL® 380 is a hydrophilic fumed silica with a specific surface area of 380 m²/g.

AEROSIL® R 812 is hydrophobic fumed silica grade treated with HMDS (Hexamethyldisilazane). It can be used for sedimentation stabilization and due to its high hydrophobicity as defoaming agent.

SIPERNAT® 500 LS is a very finely ground silica with high surface area, low drying loss and particulary high absorbency.
