SiSiB® PC8132


SiSiB® PC8132 is a colourless, low-viscosity liquid. SiSiB® PC8132 is regarded as trifunctional since all three alkoxy groups can hydrolyze. 

SiSiB® PC8132 phenylsilane also contains a phenyl group that exhibits excellent thermal stability and brings flexibility to sol-gel coating systems. It is the quivalent of ShinEtsu's KBE-103.

  • SiSiB® PC8132 is used to modify the suface of inorganic fillers such as wollastonite and aluminum trihydroxide. It makes the surface of these inorganic fillers more hydrophobic and thus increases their dispersability in mineral-filled silicone polymers. SiSiB® PC8132 is especially suited for polymers that are processed at elevated temperatures. SiSiB® PC8132 reduces the viscosity of the polymer melt.

  • SiSiB® PC8132 reacts slower with water than SiSiB® PC8131.

  • SiSiB® PC8132 can be used as a crosslinker in high-temperature silicone elastomers

  • In many sol-gel applications SiSiB® PC8132 is partially hydrolyzed to form a preproduct that can be further crosslinked using temperature. This pre-hydrolysis is often made in conjunction with alkyl silanes (SiSiB® PC5132) or other silanes (e.g. SiSiB® PC3100), silicic acid esters, or even an aqueous silica sol.

  • SiSiB® PC8132 can be used as a stereo-regulator for Ziegler-Natta-catalysts to increase the isotactic index in polypropylene. (A donor)

Packing and Storage

  • SiSiB® PC8132 is supplied in 190Kg steel drum.

  • In the unopened original container SiSiB® PC8132 has a shelf life of one year in a dry and cool place.
