CAS 1067-57-8

Butyltrimethoxysilane

Description:

Butyltrimethoxysilane, with the CAS number 1067-57-8, is an organosilicon compound characterized by its silane structure, which includes a butyl 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 ability to act as a coupling agent and surface modifier, enhancing adhesion between organic materials and inorganic substrates. Butyltrimethoxysilane is soluble in organic solvents and can hydrolyze in the presence of moisture, forming silanol groups that can further react to create siloxane bonds. This property makes it valuable in various applications, including sealants, coatings, and adhesives, where it improves durability and water resistance. Additionally, it is utilized in the production of silicone polymers and as a surface treatment agent in the manufacturing of glass, ceramics, and metals. Safety precautions should be observed 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.

N-Butyltrimethoxysilane

CAS: 1067-57-8

N-Butyltrimethoxysilane is a reactive molecule that has been used as a catalyst in the synthesis of polymers and pharmaceuticals. It is also used in the production of coatings, adhesives, and sealants. N-Butyltrimethoxysilane is soluble in organic solvents such as trifluoroacetic acid and can be used for the preparation of solid catalysts. It reacts with hydrogen fluoride to produce hydrofluoric acid, but does not react with hydrogen gas or fatty acids. The chemical structure of N-butyltrimethoxysilane includes a hydroxyl group, which allows it to form hydrogen bonds with other molecules.
