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.
