Silane OSi-PTMO is an essential agent used in
industries as below:
 Phenyltrimethoxysilane can be used as other
silanes and siloxanes intermediates and can be
used as hydrophobic additive to other silane
coupling agents.
 OSi-PTMO is used to modify the surface of
inorganic fillers such as wollastonite and
aluminum trihydroxide. It makes the surface of
these inorganic fillers more hydrophobic and
thus increases their dispersibility in
mineral-filled polymers. It is especially suited for
polymers that are processed at elevated
temperatures.
 Phenyl functional silane can improve thermal
stability of other silanes
 Phenyltrimethoxysilane can reduce the viscosity
of the polymer melt in many sol-gel applications.
It 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.
