1H,1H,2H,2H-perfluorodecyl dichloromethylsilane

Description:

1H,1H,2H,2H-Perfluorodecyl dichloromethylsilane, with CAS number 3102-79-2, is a silane compound characterized by its unique structure that includes a perfluorinated alkyl chain and dichloromethyl functional groups. This compound is typically used in surface modification applications due to its ability to impart hydrophobic and oleophobic properties to various substrates. The presence of the perfluorinated chain enhances its chemical stability and resistance to solvents, while the dichloromethyl groups allow for further chemical reactivity, enabling covalent bonding to surfaces. It is a colorless liquid at room temperature and has a low volatility, making it suitable for applications in coatings and treatments where durability is essential. Additionally, the compound's fluorinated nature contributes to its low surface energy, making it effective in reducing surface tension and preventing adhesion of contaminants. Safety precautions should be observed when handling this compound, as it may pose health risks if inhaled or ingested, and proper disposal methods should be followed to mitigate environmental impact.

Fluorinated 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.
