Vinyltriethoxysilane

Description:

Vinyltriethoxysilane, with the CAS number 78-08-0, is an organosilicon compound characterized by its vinyl group and three ethoxy 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 in the presence of moisture, where it can undergo hydrolysis to form silanol groups, which can further condense to create siloxane networks. Vinyltriethoxysilane is commonly used as a coupling agent in the formulation of adhesives, sealants, and coatings, enhancing the adhesion between organic materials and inorganic substrates. Its vinyl functionality allows for further polymerization, making it useful in the production of silicone-based polymers and composites. Additionally, it exhibits good compatibility with various organic solvents and can improve the mechanical and thermal properties of materials when incorporated into polymer matrices. 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.

Olefin Functional Trialkoxy Silane
Silane coupling agents have the ability to form a durable bond between organic and inorganic materials to generate desired heterogeneous environments or to incorporate the bulk properties of different phases into a uniform composite structure. The general formula has two classes of functionality. The hydrolyzable group forms stable condensation products with siliceous surfaces and other oxides such as those of aluminum, zirconium, tin, titanium, and nickel. The organofunctional group alters the wetting or adhesion characteristics of the substrate, utilizes the substrate to catalyze chemical transformations at the heterogeneous interface, orders the interfacial region, or modifies its partition characteristics, and significantly effects the covalent bond between organic and inorganic materials.
Alkenylsilane Cross-Coupling Agent
The cross-coupling reaction is a highly useful methodology for the formation of carbon-carbon bonds. It involves two reagents, with one typically being a suitable organometallic reagent - the nucleophile - and the other a suitable organic substrate, normally an unsaturated halide, tosylate or similar - the electrophile.
