CAS 1067-25-0

Propyltrimethoxysilane

Description:

Propyltrimethoxysilane, with the CAS number 1067-25-0, is an organosilicon compound characterized by its silane structure, which includes a propyl group and three methoxy groups attached to a silicon atom. This compound is typically a colorless to pale yellow liquid with a mild odor. It is known for its excellent adhesion properties, making it useful as a coupling agent in various applications, including coatings, sealants, and adhesives. Propyltrimethoxysilane can enhance the bonding between organic materials and inorganic substrates, such as glass and metals. It is also hydrophobic, which contributes to its effectiveness in improving water resistance in formulations. Additionally, this silane can undergo hydrolysis in the presence of moisture, leading to the formation of silanol groups that can further react with surfaces to create durable siloxane bonds. Due to its reactivity, it is important to handle this compound with care, ensuring proper storage and usage conditions to maintain its stability and effectiveness in applications.

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.
