SiSiB® PC6130


SiSiB® PC6130 is a vinyl-functional coupling agent that promotes adhesion among unsaturated, polyester-type resins or crosslinked polyethylene resins or elastomers and inorganic substrates, including fiber glass, silica, silicates and many metal oxides. When used as coupling agent, it reduces the sensitivity of the products’ mechanical and electrical properties to heat and/or moisture. 

SiSiB® PC6130 vinyl silane is the equivalent of Momentive's A-172, Wacker's GF58, Evonik's Dynasylan VTMOEO silane.

Reactivity: In the presence of moisture the methoxyethoxy groups of SiSiB® PC6130 hydrolyze to produce 2-methoxyethanol 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® PC6130 can also react with a suitable polymer (activated by peroxide or radiation).


  • SiSiB® PC6130 is used as an efficient adhesion promoter for various mineral-filled polymers, improving mechanical and electrical properties especially after exposure to moisture.

  • SiSiB® PC6130 silane coupling agent 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® PC6130 is used to improve the compatibility of fillers with polymers, leading to a better dispersibility, reduced melt viscosity and easier processing of filled plastics.

  • SiSiB® PC6130 is used to pretreat of glass, metals, or ceramic surfaces, improve the adhesion of silicone coatings on these surfaces and corrosion resistance.

Packing and Storage

  • SiSiB® PC6130 is supplied in 200Kg steel drum or 1000Kg IBC container.

  • In the unopened original container SiSiB® PC6130 has a shelf life of one year in a dry and cool place.
