- CAS Number
- 112926-00-8
- EC Number
- 601-214-2
- INCI Name
- Silica Dimethyl Silylate
- Chemical Family
- Silica
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.
