LS-M59 1H,1H,2H,2H-Nonafluorohexyltrimethoxysilane
CAS NO. 85877-79-8

1H,1H,2H,2H-Nonafluorohexyltrimethoxysilane is a chemical compound (C9H13F9O3Si) used as a versatile silane coupling agent in industrial applications. Its distinctive structure includes a nonafluorohexyl group attached to a silicon atom with three trimethoxysilane (Si(OMe)3) groups. This compound is crucial in enhancing adhesion between organic and inorganic materials. It is employed in a range of applications such as coatings, adhesives, and surface modification processes, where it significantly improves material compatibility and durability. Its unique fluorinated structure provides hydrophobic properties, making it useful for creating water-repellent and stain-resistant surfaces.
