Ethyltriacetoxysilane: The Core Power Behind Efficient Crosslinking

In the world of materials chemistry, ethyltriacetoxysilane stands out with its unique performance advantages!

Basic Information
Chinese Name: 乙基三乙酰氧基硅烷
English Name: Ethyltriacetoxysilane
CAS Number: 78-07-9
Molecular Formula: C₈H₂₀O₉Si

Key Features
Appearance: Clear and pure, a colorless to pale yellow transparent liquid
Purity: ≥90.0%, ensuring high-quality and reliable performance

Application Advantages
Compared to alkoxysilanes, it offers significantly higher reactivity, making it a key raw material for the production of RTV-1 silicone sealants. When added to silanol-terminated PDMS systems, it introduces acetoxy groups to the ends of the PDMS chains. Upon exposure to moisture, these acetoxy groups rapidly hydrolyze and crosslink, driven by the formation of acetic acid, quickly building a stable structure and giving the sealant outstanding performance.
