CAS 4518-94-9
:Propylmethyldichlorosilane
Description:
Propylmethyldichlorosilane, with the CAS number 4518-94-9, is an organosilicon compound characterized by the presence of a propyl group, a methyl group, and two chlorine atoms attached to a silicon atom. This compound typically appears as a colorless to pale yellow liquid and is known for its reactivity, particularly in hydrolysis reactions where it can react with water to form silanol and hydrochloric acid. It is used primarily in the synthesis of silicone polymers and as a coupling agent in various applications, including coatings, adhesives, and sealants. The presence of chlorine atoms enhances its reactivity, making it useful in chemical modifications and surface treatments. Safety precautions are essential when handling this substance, as it can be corrosive and harmful if inhaled or ingested. Proper storage in a cool, dry place away from moisture is recommended to maintain its stability and prevent unwanted reactions.

CAS:<p>Alkyl Silane - Conventional Surface Bonding<br>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.
