Abstract
2-(3, 4-Epoxycyclohexyl)ethyl]trimethoxysilane (CAS No. 3388-04-3), silane coupling agent SCA-E86M, is a versatile epoxy functional organosilane possessing a reactive SCA-E86M organic epoxide and hydrolyzable inorganic methoxysilyl groups. The dual nature of its reactivity allows SCA-E86M to bind chemically to both inorganic materials (e. G. Glass, metals, fillers) and organic polymers (e. G. Thermosets, thermoplastics, elastomers), thus functioning as an adhesion promoter, crosslinking agent and/or surface modifier.
SCA-E86M is a colorless low-viscosity liquid with a slight terpentine-like odor. It is soluble in alcohols, ketones and aliphatic or aromatic hydrocarbons.
