Comparing Methylsilanetriyl Triacetate and Methyltriacetoxysilane

When comparing Methylsilanetriacetate and Methyltriacetosilane, one must remember that these chemicals are highly reactive. This is because when exposed to moisture, they hydrolyze and form silanols. These silanols are capable of binding to inorganic substrates.

INNO SPECIALTY CHEMICALS is Methylsilanetriyl triacetate (CAS:4253-34-3) manufacturer and Methyltriacetoxysilane supplier in China, contact us for more information.


Methylsilanetriactone and methyltriacetoxysilane are both aqueous solutions with a distinctive vinegar-like odor. These chemicals are highly reactive and undergo rapid hydrolysis when exposed to moisture. This property is particularly important for the synthesis of polymer coatings and other materials, especially for organic solvents.

In vivo, alkyl silanols condense to form siloxane oligomers at high temperatures. These structures change with pH and concentration and evolve until equilibrium or precipitation occurs. In animals, ethyltriacetoxysilane rapidly hydrolyzes. Even low concentrations of the product have caused stomach lesions, which resemble those caused by acetic acid toxicity.

Methylsilanetriacétoxysilane is highly toxic to animals, with acute toxicity recorded at up to 50-450 mg/kg body weight in rats. Clinical signs of exposure include decreased body weight, labored breathing, salivation, and red urination. Furthermore, methylsilanetriacetoxysilane is a respiratory irritant, based on the production of acetic acid.


Methyltriacetoxysilane is a colorless liquid with a pronounced vinegar smell. It hydrolyzes in the presence of moisture to form silanols. These compounds react with each other to form siloxanes and bind to inorganic substrates. Their environmental effects depend on their industrial uses and conditions of use.
