Description

2,2,3,3,4,4,5,5,6,6,6-undecafluoro-N-(3-trimethoxysilylpropyl)hexanamide is a highly specialized fluorinated silane compound designed for advanced surface modification and functionalization applications. This unique chemical features a perfluorohexanamide moiety coupled with a trimethoxysilylpropyl group, offering exceptional hydrophobic, oleophobic, and chemical resistance properties. The molecular formula C₁₂H₁₆F₁₁NO₄Si reflects its complex structure, making it ideal for creating durable, low-energy surfaces. The trimethoxysilyl functionality enables covalent bonding to hydroxylated substrates such as glass, metals, and ceramics, while the perfluorinated tail provides outstanding repellency against water, oils, and organic solvents. This product is supplied as a technical-grade material suitable for research and industrial applications requiring precise surface engineering.

Handling of this compound should be performed under controlled conditions due to its reactive silane group and fluorinated nature. Proper personal protective equipment (PPE) including gloves and eye protection is recommended. Store in a cool, dry place away from moisture to prevent premature hydrolysis of the trimethoxysilyl groups.
