LS-E517 1H,1H,2H,2H-Perfluorodecyltriethoxysilane
CAS NO. 101947-16-4
Silfluo LS-E517 is 1H,1H,2H,2H-Perfluorodecyltriethoxysilane, a long-chain fluoroalkyl-functional triethoxysilane.
The molecule contains a C₈F₁₇ perfluorinated segment and three hydrolyzable ethoxy groups on silicon.
The triethoxysilyl group hydrolyzes and condenses with hydroxylated inorganic surfaces including glass, ceramics, silica, and metal oxides.
Compared with methoxy-functional analogs, the ethoxy groups release ethanol rather than methanol during hydrolysis.
The fluoroalkyl chain reduces surface energy and contributes to water- and oil-repellent character in selected coating systems.
Used in anti-fingerprint, easy-to-clean, anti-smudge, and low-surface-energy coating formulations.
Performance equivalent to Shin-Etsu KBE-7803.
