Product Description
Silicone rubber Cas No. 25085-34-1
CFS-F(H) is a methyl hydrogen silicone oil in which some methyl radicals of dimethyl silicone oil are replaced by hydrogen. With several reactive Si-H bonds, CFS-F(H) is mainly used as hydrophobing agent for silicas, powders and fillers. Methyl hydrogen silicone oil is a colorless, odorless, tasteless, non-toxic and transparent liquid, also known as methyl hydrogen silicone fluid, Polymethylhydrogensiloxane or Methylhydrogenpolysiloxane.
