Methyltrichlorosilane

Description:

Methyltrichlorosilane, with the CAS number 75-79-6, is an organosilicon compound characterized by its chemical formula CH3SiCl3. It appears as a colorless to pale yellow liquid with a pungent odor. This compound is notable for its reactivity, particularly in hydrolysis, where it reacts with water to produce silanol and hydrochloric acid, making it useful in the synthesis of silicone polymers and coatings. Methyltrichlorosilane is also employed in the production of silane coupling agents, which enhance the adhesion of organic materials to inorganic substrates. It has a relatively low boiling point and is volatile, which necessitates careful handling to avoid inhalation or skin contact. Additionally, it is classified as a hazardous material due to its corrosive nature and potential environmental impact. Proper storage in a cool, dry place away from moisture is essential to maintain its stability and prevent unwanted reactions. Overall, methyltrichlorosilane is a versatile compound with significant applications in materials science and chemical manufacturing.

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.
