Applications:

· Used in the fiberglass treatment industry, formulated into sizing solutions for treating fiberglass. It improves compatibility between fiberglass and polymers, enhances dispersion, and thereby increases the mechanical properties of fiberglass-reinforced composites.

· Acts as an alkylation agent and can replace trimethylchlorosilane as a trimethylsilylating reagent. It can also be used as a chain-stopping agent for silicones such as silicone oil.

· Can replace hexamethyldisiloxane as a surface treatment agent for modified powders, offering advantages such as higher safety, better stability, and strong silylation capability.

· Has been applied in the synthesis of optically active β-alkoxy ketones (e.g., camphor-type β-alkoxy-β-unsaturated ketones) for use in pharmaceutical synthesis.
