1,3-dicloro-1,1,3,3-tetrametildisilossano

Descrizione:

1,3-dicloro-1,1,3,3-tetrametildisilossano è un composto chimico caratterizzato dalla sua struttura di silossano, che consiste in legami silicio-ossigeno (Si-O). Questo composto presenta due atomi di cloro e quattro gruppi metilici attaccati agli atomi di silicio, contribuendo alle sue proprietà uniche. È tipicamente un liquido incolore o giallo pallido con una viscosità relativamente bassa. La presenza di atomi di cloro ne aumenta la reattività, rendendolo utile in varie applicazioni chimiche, inclusa come precursore nella sintesi di polimeri di silicone e come potenziale intermedio nella sintesi organica. La sua struttura molecolare consente flessibilità e stabilità, che sono importanti per le sue prestazioni nelle applicazioni industriali. Inoltre, può presentare bassa volatilità e solubilità moderata in solventi organici. Le considerazioni di sicurezza includono maneggiarlo con cura a causa della sua potenziale tossicità e impatto ambientale, in particolare riguardo alla sua natura clorurata. Dovrebbero essere seguiti metodi adeguati di stoccaggio e smaltimento per mitigare eventuali rischi associati al suo utilizzo.

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.
