Informação sobre produto

• Nome: METHYLTRICHLOROSILANE, 99% 55-GAL DRUM
• Marca: Gelest
• Descrição: 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.Methyltrichlorosilane; Trichloromethylsilane; TrichlorosilylmethaneViscosity: 0.46 cStΔHvap: 31.0 kJ/molSurface tension: 20.3 mN/mIonization potential: 11.36 eVSpecific heat: 0.92 J/g/°Vapor pressure, 13.5 °C: 100 mmCritical temperature: 243 °CCritical pressure: 39 atmCoefficient of thermal expansion: 1.3 x 10-3Fundamental builing-block for silicone resinsForms silicon carbide by pyrolysisIn a synergistic fashion with boron trifluoride etherate catalyzes the crossed imino aldehyde pinacol couplingIn combination with H2 forms SiC by CVDStandard grade available, SIM6520.0
