SiSiB® PC8131 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 polymers.

SiSiB® PC8131 is especially suited for polymers that are processed at elevated temperatures. SiSiB® PC8131 reduces the viscosity of the polymer melt.

In many sol-gel applications SiSiB® PC8131 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 organofunctional silanes (e.g. SiSiB® PC3100), silicic acid esters, or even an aqueous silica sol.

SiSiB® PC8131 reacts faster with water than SiSiB® PC8132.
