Products

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

SIPERNAT® 50 S is a hydrophilic, finely milled silica. Besides its application as flow aid and highly effective anticaking agent it also may serve as carrier of especially high absorptive capacity in case particle fineness is required.

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® 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® 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.

AEROSIL® R 8200 is a structure modified hydrophobic silica grade treated with HMDS (Hexamethyldisilazane). It is characterized by an extremely low thickening effect and high compacted bulk density. Its high hydrophobicity makes it suitable as a defoamer silica.

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.

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

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

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

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.
