Product Description

Abstract
3-Glycidoxypropyltriethoxysilane (CAS No. 2602-34-8), Silane coupling agent KH-561, is a versatile epoxy functional organosilane possessing a reactive organic epoxide and hydrolyzable inorganic methoxysilyl groups. The dual nature of its reactivity allows KH-561 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.
KH-561 is a colorless low-viscosity liquid with a slight terpentine-like odor. It is soluble in alcohols, ketones and aliphatic or aromatic hydrocarbons.
