Application

DP-811 is used to modify the suface of inorganic fillers such as wollastonite andaluminum trihydroxide. It makes the surface of these inorganic fillers more hydrophobic and thus increases their dispersability in mineral-filled polymers. DP-811 is especially suited for polymers that are processed at elevated temperatures. DP-811 reduces the viscosity of the polymer melt.

In many sol-gel applications DP-811 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 or other organofunctional silanes , silicic acid esters, or even an aqueous silica sol.

DP-811 can be used as a crosslinker in high-temperature silicone elastomers

DP-811 can be used as a stereo-regulator for Ziegler-Natta-catalysts to increase the isotactic index in polypropylene. (A donor)
