CAS 5314-55-6

Ethyltrimethoxysilane

Description:

Ethyltrimethoxysilane, with the CAS number 5314-55-6, is an organosilicon compound characterized by its silane structure, which includes an ethyl 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 reactivity, particularly its ability to hydrolyze in the presence of moisture, forming silanol groups that can further condense to create siloxane networks. Ethyltrimethoxysilane is commonly used as a coupling agent, adhesion promoter, and surface modifier in various applications, including coatings, sealants, and composites. Its properties allow it to enhance the bonding between organic materials and inorganic substrates, improving durability and performance. Additionally, it exhibits good compatibility with a range of organic solvents and can be utilized in the formulation of silane-based products for improved water repellency and chemical resistance. Safety precautions should be taken when handling this compound, as it can be irritating to the skin and eyes.

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.
