| Hazard Information | Back Directory | [Chemical Properties]
clear colorless liquid | [General Description]
Ethoxytrimethylsilane (ETMS) is an alkoxysilane that is used as a capping agent, which can tune the hydrophobic properties for a variety of substrates by coupling with the surface hydroxyl groups. |
| Questions and Answers (Q&A) | Back Directory | [Uses]
Ethoxytrimethylsilane is also called Trimethylethoxysilane, an intermediate useful for blocking hydroxyl or amino groups to perform reactions on multi-functional organic compounds or polymers. It is also useful for deactivating glass surfaces used in gas chromatographic applications.
