Methyltriacetoxysilane Chemical Properties,Uses,Production
Chemical Properties
Methyltriacetoxysilane (MTAC) 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.
Uses
Methyltriacetoxysilane is used as a silane coupling agent.
Flammability and Explosibility
Not classified
Toxics Screening Level
The initial threshold screening level (ITSL) for methyltriacetoxysilane (CASRN 4253-34-3) remains at 0.1 μg/m3 based on an annual averaging time.
