HD-172 It is a medium surface area hydrophobic fumed silica that has beensurface-modified with polydimethylsiloxane. This treatment makes it
extremely hydrophobic and has very different properties comparedtonon-treated silica. It has good enhancement and thixotropic effect, canbeused in silicone rubber, silicone sealant, paint and coatings, adhesives, printingink and so on
CAS：1333-86-4
