CAS: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. ω-Butylpoly(dimethylsiloxanyl)ethyltriethoxysilane; α-Butyl-ω-triethoxysilylethyl terminated polydimethylsiloxane 5-8 (Me2SiO)Hydrophobic surface treatmentFórmula:C24H52O3SiForma y color:Straw LiquidPeso molecular:416.76Octadecyltriethoxysilane

CAS:Octadecyltriethoxysilane is a white powder with the chemical formula (C8H17)3SiO. It is used as an additive in paint, coatings, and sealants to provide a protective barrier or to improve the surface properties of zirconium oxide. Octadecyltriethoxysilane also has analytical applications in electrochemical impedance spectroscopy and fluorescence probe techniques. In addition, octadecyltriethoxysilane can be used as a hydrochloric acid scavenger in chromatographic processes. Octadecyltriethoxysilane is made of hydrocarbons that are linked together by silicon-oxygen bonds. The synthesis of octadecyltriethoxysilane begins with the reaction of tetraethyl orthosilicate (TEOS) with three equivalents of octadecene, followed by hydrolysis and condensation reactions: This process resultsPureza:Min. 95%Ref: 3D-FO62930
