Triethoxymethylsilane

Description:

Triethoxymethylsilane, with the CAS number 2031-67-6, is an organosilicon compound characterized by its silane structure, which includes three ethoxy groups and a methylene group 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 in hydrolysis, where it can form silanol groups upon exposure to moisture, leading to the formation of siloxane networks. Triethoxymethylsilane is often used as a coupling agent, adhesion promoter, or crosslinking agent in various applications, including coatings, sealants, and adhesives. Its ability to bond organic materials to inorganic substrates makes it valuable in enhancing the durability and performance of composite materials. Additionally, it exhibits good compatibility with a range of organic solvents and can improve the hydrophobic properties of surfaces. Safety precautions should be taken when handling this compound, as it can be irritating to the skin and eyes, and proper ventilation is recommended due to its volatile nature.

METHYLTRIETHOXYSILANE

CAS: 2031-67-6

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.
