SiSiB® PC5881

Octadecylsilane
SiSiB® PC5881 is a long-chain alkyl silane, commonly called OTMS. It is easy to be dissolved in ordinary organic solvent, e.g. hydrocarbon, ether, ketone, etc. It is easy to be hydrolyzed and condensed, generate polysiloxane.
SiSiB® PC5881 silane reducing agent is used for preparing hydrophobic coatings and self-assembled monolayers. It is sensitive toward water, irreversibly degrading to a siloxane polymer. It places a C18H39SiO3 "cap" on oxide surfaces. The formation of OTMS monolayers is used for converting hydrophilic surfaces to hydrophobic surfaces, e.g. for use in certain areas of nanotechnology and analytical chemistry.
