Chlorodimethyloctylsilane

Description:

Chlorodimethyloctylsilane, with the CAS number 18162-84-0, is an organosilicon compound characterized by its silane structure, which includes a silicon atom bonded to two dimethyl groups and an octyl group, along with a chlorine atom. This compound is typically a colorless to pale yellow liquid with a distinctive odor. It is known for its reactivity, particularly due to the presence of the chlorine atom, which can participate in various chemical reactions, including hydrolysis and condensation. Chlorodimethyloctylsilane is often used as a coupling agent or surface modifier in various applications, including the production of silicone polymers and coatings. Its hydrophobic properties make it suitable for enhancing the water resistance of materials. Additionally, it can be utilized in the synthesis of other organosilicon compounds. Safety precautions should be taken when handling this substance, as it can be irritating to the skin and eyes, and proper storage conditions are necessary to maintain its stability and effectiveness.

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.
