What is Ethoxytrimethylsilane?
Chemical properties
clear colorless liquid
The Uses of Ethoxytrimethylsilane
Ethoxytrimethylsilane is used in preparation method of solvent-free heavy peeling regulator for silicon release.
The Uses of Ethoxytrimethylsilane
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.
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.
