(Dodecyl)(methyl)dichlorosilane

Description:

(Dodecyl)(methyl)dichlorosilane, with the CAS number 18407-07-3, is an organosilicon compound characterized by its long hydrophobic dodecyl chain and two chlorosilane functional groups. This compound typically appears as a colorless to pale yellow liquid and is known for its ability to form siloxane bonds upon hydrolysis, making it useful in surface modification and as a coupling agent in various applications. The presence of the dodecyl group imparts significant hydrophobic properties, while the dichlorosilane functionality allows for reactivity with various substrates, facilitating the attachment of the silane to surfaces such as glass, metals, and polymers. Its applications span across fields such as coatings, adhesives, and sealants, where it enhances water repellency and improves adhesion. Additionally, due to its chlorosilane nature, it can release hydrochloric acid upon hydrolysis, necessitating careful handling and storage. Overall, (Dodecyl)(methyl)dichlorosilane is valued for its unique combination of hydrophobicity and reactivity, making it a versatile compound in materials science.

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.
