1,3-dichloro-1,1,3,3-tetramethyldisiloxane

Description:

1,3-Dichloro-1,1,3,3-tetramethyldisiloxane is a chemical compound characterized by its siloxane backbone, which consists of silicon-oxygen (Si-O) linkages. This compound features two chlorine atoms and four methyl groups attached to the silicon atoms, contributing to its unique properties. It is typically a colorless to pale yellow liquid with a relatively low viscosity. The presence of chlorine atoms enhances its reactivity, making it useful in various chemical applications, including as a precursor in the synthesis of silicone polymers and as a potential intermediate in organic synthesis. Its molecular structure allows for flexibility and stability, which are important for its performance in industrial applications. Additionally, it may exhibit low volatility and moderate solubility in organic solvents. Safety considerations include handling it with care due to its potential toxicity and environmental impact, particularly regarding its chlorinated nature. Proper storage and disposal methods should be followed to mitigate any risks associated with its use.

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.
