| | Methyltriacetoxysilane Usage And Synthesis |
| 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. |
