SiSiB® PC6110


SiSiB® PC6110, vinyltrimethoxysilane, is used as a polymer modifier via grafting reactions. The resulting pendant trimethoxysilyl groups can function as moisture-activated crosslinking sites. The Silane grafted polymer is processed as a thermoplastic and crosslinking occurs after fabrication of the finished article upon exposure to moisture.

SiSiB® PC6110 vinyl silane is the equivalent of Momentive's A-171, Dow's Z-6300, Wacker's  XL10, Evonik's Dynasylan VTMO, ShinEtsu's KBM-1003 silane.

Reactivity: In the presence of moisture the methoxy groups of SiSiB® PC6110 hydrolyze to produce methanol and reactive silanol (Si-OH) groups which can bond to a variety of inorganic substrates or react with each other to form siloxane bonds (Si-O-Si). The organophilic vinyl end of SiSiB® PC6110 can also react with a suitable polymer (activated by peroxide or radiation).


  • SiSiB® PC6110 is suitable for the preparation of moisture-curing polymers, e.g. polyethylene. Silane crosslinked polyethylene is widely used as cable isolation, and sheathing mainly in low voltage applications as well as for hot water/sanitary silicone pipes and underfloor heating.

  • SiSiB® PC6110 is used as a co-monomer for the preparation of different polymers such as polyethylene or acrylics. Those polymers show an improved adhesion to inorganic surfaces and they can also be crosslinked with moisture.

  • SiSiB® PC6110 is used as an efficient adhesion promoter for various mineral-filled polymers, improving mechanical and electrical properties especially after exposure to moisture.

  • SiSiB® PC6110 is used to improve the compatibility of fillers with silicone polymers, leading to a better dispersibility, reduced melt viscosity and easier processing of filled plastics.

  • SiSiB® PC6110 is used to pretreat of glass, metals, or ceramic surfaces, improve the adhesion of coatings on these surfaces and corrosion resistance.

  • SiSiB® PC6110 is used as moisture scavenger. SiSiB® PC6110 reacts rapidly with water. This effect is used widely in sealants.

Packing and Storage

  • SiSiB® PC6110 vinyltrimethoxysilane is supplied in 190Kg steel drum or 950Kg IBC container.

  • In the unopened original container SiSiB® PC6110 (VTMO silane, CAS 2768-02-7) has a shelf life of one year in a dry and cool place.
