CAS 14799-94-1: Dichlorohexylmethylsilane

Dichlorohexylmethylsilane is a cationic polymerization agent that reacts with hydrochloric acid to form a polymer. It is used as a cross-linking agent to produce polymers with high molecular weight and good chemical stability. Dichlorohexylmethylsilane is not reactive with ethyl chloride, but can react with chlorine atoms to form chlorosilanes. Dichlorohexylmethylsilane has a particle size of 0.5-5 μm which makes it well suited for use in flow systems and potential use as a reactive site for hydrogen chloride.

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.
