CAS 38051-57-9

Chlorodecyldimethylsilane

Description:

Chlorodecyldimethylsilane, with the CAS number 38051-57-9, is an organosilicon compound characterized by the presence of a chlorodecyl group attached to a dimethylsilane moiety. This compound typically appears as a colorless to pale yellow liquid and is known for its reactivity due to the presence of the chlorine atom, which can participate in various chemical reactions, including nucleophilic substitution. It is often used as a silane coupling agent, enhancing adhesion between organic materials and inorganic substrates, particularly in coatings and sealants. The presence of the long alkyl chain (decyl) contributes to its hydrophobic properties, making it useful in applications requiring water repellency. Additionally, chlorodecyldimethylsilane can be utilized in surface modification processes, improving the compatibility of materials in composite formulations. Safety considerations include handling it in a well-ventilated area and using appropriate personal protective equipment, as it may be irritating to skin and eyes and can release harmful gases upon hydrolysis.

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.
