• Marchio: Gelest
• Descrizione: Fluorinated Alkyl Silane - Conventional Surface BondingAliphatic, 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.(Heptadecafluoro-1,1,2,2-tetrahydrodecyl)trimethoxysilane; (1H,1H,2H,2H-Perfluorodecyl)trimethoxysilane; HeptadecafluorodecyltrimethoxysilanePackaged over copper powderTreated surface contact angle, water: 115 °Cγc of treated surfaces: 12 mN/mSurface modification of titanium and silica substrates reduces coefficient of frictionForms inorganic hybrids with photoinduceable refractive index reductionTrialkoxy silane
