LS-E513 1H,1H,2H,2H-Perfluorooctyltriethoxysilane
CAS NO. 51851-37-7
Silfluo LS-E513 is 1H,1H,2H,2H-Perfluorooctyltriethoxysilane, a fluoroalkyl-functional triethoxysilane.
The molecule contains a C₆ tridecafluorooctyl carbon chain 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, anti-smudge, easy-to-clean, anti-graffiti, and low-surface-energy coating formulations.
Performance equivalent to Evonik Dynasylan F 8261 and Shin-Etsu KBE-7103.
