2-(3,4-Epoxycyclohexyl) Ethyl]trimethoxysilane Description
2-(3,4-Epoxycyclohexyl) Ethyltrimethoxysilane (CAS 3388-04-3), also known as Trimethoxy[2-(7-oxabicyclo[4.1.0]hept-3-yl)ethyl]silane, is a colorless, low-viscosity liquid with a faint turpentine odor. It is soluble in alcohols, ketones, and both aliphatic and aromatic hydrocarbons.
This epoxy-functional organosilane (CAS 3388-04-3) features reactive organic epoxide and hydrolyzable methoxysilane groups. Its dual reactivity enables it to chemically bond with inorganic materials like glass, metals, and fillers, as well as organic polymers such as thermosets, thermoplastics, and elastomers. It functions as an adhesion promoter, cross-linker, and surface modifier in various industrial applications.
