LS-M12 Diphenyldimethoxysilane
CAS NO. 6843-66-9
Silfluo LS-M12 is Diphenyldimethoxysilane, a bifunctional phenyl-functional dimethoxysilane.
The molecule contains two phenyl groups and two hydrolyzable methoxy groups on silicon.
The difunctional methoxy structure enables controlled linear chain extension and condensation without introducing trifunctional crosslinking sites.
The dual phenyl substitution raises refractive index, thermal stability, and UV resistance of derived siloxane networks relative to mono-phenyl analogs.
Used as reactive intermediate in phenyl silicone polymer synthesis, as external electron donor in Ziegler-Natta polyolefin catalysis, and as electrolyte additive in lithium-ion battery systems.
Performance equivalent to Evonik Dynasylan 6010, Shin-Etsu KBM-202SS, and Dow AY43-047 / Z-6047.
