CAS 3069-19-0: Hexyltrimethoxysilane

Alkyl Silane - Conventional Surface Bonding Aliphatic, fluorinated aliphatic or substituted aromatic hydrocarbon substituents are the hydrophobic entities which enable silanes to induce surface hydrophobicity. The organic substitution of the silane must be non-polar. The hydrophobic effect of the organic substitution can be related to the free energy of transfer of hydrocarbon molecules from an aqueous phase to a homogeneous hydrocarbon phase. A successful hydrophobic coating must eliminate or mitigate hydrogen bonding and shield polar surfaces from interaction with water by creating a non-polar interphase. Although silane and silicone derived coatings are in general the most hydrophobic, they maintain a high degree of permeability to water vapor. This allows coatings to breathe and reduce deterioration at the coating interface associated with entrapped water. Since ions are not transported through non-polar silane and silicone coatings, they offer protection to composite structures ranging from pigmented coatings to rebar reinforced concrete. A selection guide for hydrophobic silanes can be found on pages 22-31 of the Hydrophobicity, Hydrophilicity and Silane Surface Modification brochure.

Hexyltrimethoxysilane

Hexyltrimethoxysilane is an organic compound that can be used in a variety of applications, including as a reactive agent in the synthesis of polymers and coatings. It has been shown to exhibit high resistance to hydrolysis and oxidation, as well as high thermal stability. Hexyltrimethoxysilane reacts with fatty acids to form esters and amides. This compound is also hydrophilic, making it useful for the transport of water-insoluble materials. Hexyltrimethoxysilane can be used as a solid catalyst for chemical reactions, such as chromatography and polymerization.
