LS-E11 Phenyltriethoxysilane (Donor A)
CAS NO. 780-69-8
Silfluo LS-E11 is Phenyltriethoxysilane, a trifunctional phenyl-functional triethoxysilane.
The molecule contains one phenyl group and three hydrolyzable ethoxy groups on silicon.
The triethoxysilyl group hydrolyzes and condenses with hydroxylated inorganic surfaces or participates in sol-gel network formation; hydrolysis releases ethanol rather than methanol.
The phenyl group raises thermal stability, refractive index, and UV resistance of derived siloxane networks relative to alkyl-functional analogs.
Used in sol-gel coating formulations, inorganic filler surface modification, high-temperature composite coupling, and phenyl silicone resin synthesis.
Performance equivalent to Dow Z-9805, Evonik Dynasylan 9265, Wacker Silan P Triethoxy, and Shin-Etsu KBE-103.
