SiSiB® PC5881

Octodecyltrimethoxysilane

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.

Application


  • Coupling Agent


  • This alkyl alkoxy silane is mainly used to deal with inorganic materials, e.g. glass, silica, Al2O3, Kaolin, pottery  and porcelain, mica, SiC, talcum powder etc., in order to improve the property of blending  with organic matter and water-proof, enhancing the mechanical property of the products.


  • Protect Historical Relics or Other Products from Water


  • Protect historical relics (esp. outdoor historical relics) from corrosion, freeze or  efflorescence.


  • Fog-proof Preparation of Glass

    Protect blank glass and coated glass (optical antireflex coating, clear silicone coating, vacuum antireflex  coating, reflective coating)

    Protect optical parts or precision instrument with graduations and metal frames.
