    Applications and Performance

    Phenyl functional silanecan improve thermal stability of other silanes.
    Phenyl functional silane can be used as other silanes and siloxanes intermediates.
    Phenyl functional silane can be used for hydrophobic surface treatment.
    Phenyl functional silane can be used as hydrophobic additive to other silane coupling agents.
    QP-921 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. QP-921 is especially suited for polymers that are processed at elevated temperatures.
    QP-921 reduces the viscosity of the polymer melt.In many sol-gel applications. QP-921 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.
