Description

Colorless or yellowish transparent liquid

Liquid

Vinyltriacetoxysilane is a clear to yellowish liquid with acrid odor of acetic acid (vinegar). It hydrolyzes in the presence of moisture (acetic acid is released) to form silanols, which can react with themselves to pro-duce siloxanes or bind to inorganic substrates.

Vinyltriacetoxysilane is an organosilicon compound used in various industrial applications due to its ability to act as a coupling agent and crosslinking agent.
