Dynasylan® VTMOEO

Technical Documents

Dynasylan® VTMOEO is a bifunctional organosilane possessing a reactive vinyl group and a hydrolyzable 2-methoxyethoxysilyl group. Acts as an efficient adhesion promoter and/or surface modifier. The dual nature of its reactivity allows Dynasylan® VTMOEO to bind chemically to both inorganic materials (e.g. glass, metals, fillers) and organic polymers (e.g. thermosets, thermoplastics, elastomers).Used in adhesives and sealants.
