What Is Ethoxysilane?
Ethoxysilane refers to a group of compounds where ethoxy groups are bonded to silicon, categorizing it as a type of alkoxide. These compounds are known for their unique chemical properties and applications.
Tetraethoxysilane, a specific type of ethoxysilane, is classified under the GHS (Globally Harmonized System of Classification and Labelling of Chemicals) as skin corrosive/irritant, eye irritant, and poses specific target organ/systemic toxicity.
Uses of Ethoxysilane
Ethoxysilane is utilized in various applications, such as protective films, etching-resistant films, insulation, and space-filling between wiring layers in electronics, and as high-k dielectric films in semiconductor devices. Its form as an alkoxide makes it a preferred choice due to its lower flammability and higher volatility compared to other organometallic compounds.
One common variant, Tetraethoxysilane, has gained recent attention as an additive in antibacterial and sanitizing sprays. In these applications, tetraethoxysilane is bonded to an antimicrobial component, functioning as an adhesive to enhance the coating ability of the antimicrobial component on various surfaces. This attribute of ethoxysilane significantly prolongs the efficacy of the antimicrobial and sanitizing agents.
