CAS 3449-28-3

Dibutyldichlorosilane

Description:

Dibutyldichlorosilane, with the CAS number 3449-28-3, is an organosilicon compound characterized by its structure, which includes two butyl groups and two chlorine atoms attached to a silicon atom. This colorless to pale yellow liquid is known for its reactivity, particularly in hydrolysis, where it can react with moisture to form silanol and hydrochloric acid. It has a relatively low boiling point and is soluble in organic solvents, making it useful in various chemical applications. Dibutyldichlorosilane is primarily utilized as a precursor in the synthesis of silicone polymers and as a coupling agent in surface modification processes. Its chemical properties allow it to participate in reactions that form siloxane bonds, which are essential in creating silicone materials. However, it is important to handle this compound with care, as it can be corrosive and poses health hazards upon exposure. Proper safety measures should be taken when working with dibutyldichlorosilane to mitigate risks associated with its chemical reactivity and potential toxicity.

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.
