LS-E59 1H,1H,2H,2H-Nonafluorohexyltriethoxysilane
CAS NO. 102390-98-7
Silfluo LS-E59 is Nonafluorohexyltriethoxysilane, a short-chain fluoroalkyl-functional triethoxysilane.
The molecule contains a C4F9 perfluoroalkyl group and three hydrolyzable ethoxy groups on silicon.
The triethoxysilyl group hydrolyzes and condenses with hydroxylated inorganic surfaces including glass, ceramics, silica, and metal oxides.
The short-chain fluoroalkyl structure provides surface energy reduction while avoiding long-chain PFOA.PFOS-regulated structures; verify regulatory compliance per local requirements and formulation composition.
Compared with methoxy-functional analogs, the ethoxy groups release ethanol rather than methanol during hydrolysis.
Used in anti-fingerprint, anti-smudge, easy-to-clean, anti-graffiti, and low-surface-energy coating formulations.
